ADS8331IBPWR

Texas Instruments · Analog To Digital Converters (ADC) · TSSOP-24

ADS8331IBPWR from Texas Instruments, in a TSSOP-24. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN1 input Mux input channel 1; absolute maximum -0.3 V to VA + 0.3 V relative to AGND.
2 IN2 input Mux input channel 2; absolute maximum -0.3 V to VA + 0.3 V relative to AGND.
3 IN3 input Mux input channel 3; absolute maximum -0.3 V to VA + 0.3 V relative to AGND.
4 NC unconnected No internal connection (ADS8331 only).
5 NC unconnected No internal connection (ADS8331 only).
6 NC unconnected No internal connection (ADS8331 only).
7 NC unconnected No internal connection (ADS8331 only).
8 RESET input External reset, active low.
9 EOC/INT/CDI bidirectional Programmable status output (EOC low during conversion by default, or INT low after end of conversion and high after FS/CS goes low, with programmable polarity), also usable as chain data input (CDI) in daisy-chain mode.
10 SCLK input SPI clock for the serial interface, up to 40 MHz at VA = VBD = 5 V.
11 FS/CS input Frame sync signal for a DSP (such as TMS320 DSP) or chip select input for SPI.
12 SDI input SPI serial data input.
13 SDO output SPI serial data output.
14 DGND power_in Digital interface ground.
15 CONVST input Conversion start input that freezes the sample and hold and starts conversion.
16 VBD power_in Digital interface supply, 1.65 V to VA + 0.2 V recommended.
17 VA power_in Analog supply, 2.7 V to 5.5 V.
18 REF+ input External reference input; absolute maximum -0.3 V to VA + 0.3 V relative to AGND.
19 REF- power_in External reference ground, to be connected to AGND through an individual via on the printed-circuit board.
20 AGND power_in Analog ground.
21 ADCIN input ADC input; absolute maximum -0.3 V to VA + 0.3 V relative to AGND.
22 MUXOUT output Mux output.
23 COM input Common ADC input, usually connected to AGND.
24 IN0 input Mux input channel 0; absolute maximum -0.3 V to VA + 0.3 V relative to AGND.
