Pinout

Pin Name Type Function
1 AVCC power_in Analog supply of 4.75 V to 5.25 V that powers the internal front-end amplifiers and ADC core and must be decoupled to AGND.
2 AGND power_in Analog ground reference for all analog circuitry and analog input and external reference signals; all six AGND pins must connect to the system AGND plane.
3 OS0 input Oversampling mode select LSB, latched on the BUSY falling edge to set the oversampling ratio for the next conversion per Table 9.
4 OS1 input Oversampling mode select bit 1, latched on the BUSY falling edge to set the oversampling ratio for the next conversion per Table 9.
5 OS2 input Oversampling mode select MSB, latched on the BUSY falling edge together with OS1 and OS0 to set the oversampling ratio per Table 9.
6 PAR/SER/BYTE SEL input Interface select: logic low selects the parallel interface, logic high selects the serial interface (DB15/BYTE SEL low) or the parallel byte interface (DB15/BYTE SEL high).
7 STBY input Standby input that, when low, selects standby (RANGE high) or shutdown (RANGE low) power-saving mode per Table 7.
8 RANGE input Analog input range select for all channels: logic high selects ±10 V and logic low selects ±5 V, and the pin should not be changed during conversion.
9 CONVST A input Conversion start input A; its rising edge holds the V1-V4 track-and-hold, and with CONVST B tied together it starts simultaneous sampling of all eight channels.
10 CONVST B input Conversion start input B; its rising edge holds the V5-V8 track-and-hold, and the maximum allowed delay between the CONVST A and CONVST B rising edges is 0.5 ms (t5).
11 RESET input Active-high reset that must be pulsed after power-up with a minimum high pulse of 50 ns (tRESET); applying it during a conversion aborts the conversion.
12 RD/SCLK input Parallel read control input RD when the parallel interface is selected, or serial clock input SCLK when the serial interface is selected.
13 CS input Active-low chip select that enables the data frame; in parallel mode CS and RD low enable DB[15:0], and in serial mode CS frames the transfer.
14 BUSY output Goes high on the CONVST rising edge and returns low when all channels finish converting, and its falling edge indicates results can be read after t4.
15 FRSTDATA output Indicates when channel V1 is being read on the parallel, byte or serial interface and is tri-stated while CS is high.
16 DB0 tri_state Parallel data output bit 0 (LSB), tri-stated unless CS and RD are low, and tied to digital ground when PAR/SER/BYTE SEL is high.
17 DB1 tri_state Parallel data output bit 1, tri-stated unless CS and RD are low, and tied to digital ground when PAR/SER/BYTE SEL is high.
18 DB2 tri_state Parallel data output bit 2, tri-stated unless CS and RD are low, and tied to digital ground when PAR/SER/BYTE SEL is high.
19 DB3 tri_state Parallel data output bit 3, tri-stated unless CS and RD are low, and tied to digital ground when PAR/SER/BYTE SEL is high.
20 DB4 tri_state Parallel data output bit 4, tri-stated unless CS and RD are low, and tied to digital ground when PAR/SER/BYTE SEL is high.
21 DB5 tri_state Parallel data output bit 5, tri-stated unless CS and RD are low, and tied to digital ground when PAR/SER/BYTE SEL is high.
22 DB6 tri_state Parallel data output bit 6, tri-stated unless CS and RD are low, and tied to digital ground when PAR/SER/BYTE SEL is high.
23 VDRIVE power_in Logic interface supply of 2.3 V to 5.25 V that sets the digital I/O logic levels and should match the host processor supply.
24 DB7/DOUTA tri_state Parallel data bit 7 (MSB of the byte in byte mode), or serial output DOUTA that carries channels V1-V4 when the serial interface is selected.
25 DB8/DOUTB tri_state Parallel data bit 8, or serial output DOUTB that carries channels V5-V8 when the serial interface is selected.
26 AGND power_in Analog ground pin associated with the analog circuitry; must connect to the system AGND plane.
27 DB9 tri_state Parallel data output bit 9, tri-stated unless CS and RD are low, and tied to digital ground when PAR/SER/BYTE SEL is high.
28 DB10 tri_state Parallel data output bit 10, tri-stated unless CS and RD are low, and tied to digital ground when PAR/SER/BYTE SEL is high.
29 DB11 tri_state Parallel data output bit 11, tri-stated unless CS and RD are low, and tied to digital ground when PAR/SER/BYTE SEL is high.
30 DB12 tri_state Parallel data output bit 12, tri-stated unless CS and RD are low, and tied to digital ground when PAR/SER/BYTE SEL is high.
31 DB13 tri_state Parallel data output bit 13 (MSB of the 14-bit result), tri-stated unless CS and RD are low, and tied to digital ground when PAR/SER/BYTE SEL is high.
32 DB14/HBEN bidirectional Parallel data bit 14 (sign extension of DB13) in parallel mode, or HBEN in byte mode selecting whether the high byte (HBEN high) or low byte (HBEN low) is output first.
33 DB15/BYTE SEL bidirectional Parallel data bit 15 (sign extension) in parallel mode, and with PAR/SER/BYTE SEL high it selects serial (low) or parallel byte (high) interface mode per Table 8.
34 REF SELECT input Reference select: logic high enables the internal 2.5 V reference, while logic low disables it and requires a 2.5 V external reference on REFIN/REFOUT.
35 AGND power_in Analog ground pin for the analog input channels; must connect to the system AGND plane.
36 REGCAP power_out Internal 2.5 V LDO regulator output that must be decoupled to AGND with a 1 µF capacitor and sits at 2.5 V to 2.7 V.
