HT9201ARSZ

HTCSEMI · Analog To Digital Converters (ADC) · SSOP-28-208mil

HT9201ARSZ from HTCSEMI, in a SSOP-28-208mil. 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 DVSS power_in Digital ground for the logic and output buffers, to be connected close to the ADC with the analog ground in a solid ground plane.
2 DVDD power_in Digital supply for the D0-D9 output buffers, operable from 2.7 V to 5.5 V independently of AVDD.
3 D0 output Bit 0 (LSB) of the straight-binary 10-bit output word, powered from DVDD, with a fan-out of one recommended and load kept below 20 pF.
4 D1 output Bit 1 of the straight-binary 10-bit output word, powered from DVDD, with load kept below 20 pF.
5 D2 output Bit 2 of the straight-binary 10-bit output word, powered from DVDD, with load kept below 20 pF.
6 D3 output Bit 3 of the straight-binary 10-bit output word, powered from DVDD, with load kept below 20 pF.
7 D4 output Bit 4 of the straight-binary 10-bit output word, powered from DVDD, with load kept below 20 pF.
8 D5 output Bit 5 of the straight-binary 10-bit output word, powered from DVDD, with load kept below 20 pF.
9 D6 output Bit 6 of the straight-binary 10-bit output word, powered from DVDD, with load kept below 20 pF.
10 D7 output Bit 7 of the straight-binary 10-bit output word, powered from DVDD, with load kept below 20 pF.
11 D8 output Bit 8 of the straight-binary 10-bit output word, powered from DVDD, with load kept below 20 pF.
12 D9 output Bit 9 (MSB) of the straight-binary 10-bit output word, powered from DVDD, with load kept below 20 pF.
13 SELECT input Selects the output channel: high presents the I-channel word and low presents the Q-channel word, with the input referenced to AVDD/2 threshold.
14 CLOCK input Sample clock input, internally buffered from AVDD with threshold at AVDD/2, with clock pulse widths high and low of 22.5 ns each for 20 MSPS operation.
15 SLEEP input Power-down control: high powers the device down and low gives normal operation.
16 INA-I input I-channel analog input A, accepting single-ended or differential signals, with an input span of 1 V to 2 V set by the reference mode.
17 INB-I input I-channel analog input B, accepting single-ended or differential signals, with an input span of 1 V to 2 V set by the reference mode.
18 REFT-I passive Top reference decoupling node for the I channel, to be bypassed with chip capacitors placed close to the converter.
19 REFB-I passive Bottom reference decoupling node for the I channel, to be bypassed with chip capacitors placed close to the converter.
20 AVSS power_in Analog ground for the converters, reference and input buffers, to be joined with DVSS near the ADC.
21 REFSENSE input Reference mode select: tie to VREF for 1 V, to AVSS for 2 V, to AVDD for external reference, or to a divider tap for a programmable 0.7 V to 2.5 V reference.
22 VREF power_in Internal reference output, 1 V or 2 V depending on REFSENSE, which becomes an input when an external reference is applied.
23 AVDD power_in Analog supply, operable from 2.7 V to 5.5 V independently of DVDD, with absolute maximum AVDD to AVSS of -0.3 V to +6.5 V.
24 REFB-Q passive Bottom reference decoupling node for the Q channel, to be bypassed with chip capacitors placed close to the converter.
25 REFT-Q passive Top reference decoupling node for the Q channel, to be bypassed with chip capacitors placed close to the converter.
26 INB-Q input Q-channel analog input B, accepting single-ended or differential signals, with an input span of 1 V to 2 V set by the reference mode.
27 INA-Q input Q-channel analog input A, accepting single-ended or differential signals, with an input span of 1 V to 2 V set by the reference mode.
28 CHIP-SELECT input High places the digital outputs in a high-impedance state for in-circuit test or evaluation, and low gives normal operation.
