ADC1175-50CIMTX

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

ADC1175-50CIMTX 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 PD input CMOS/TTL compatible power-down input; when high the device enters power-down with total power typically below 5 mW, and when low it operates normally.
2 DVSS power_in Ground return for the digital supply; connect to AVSS close to the ADC1175-50.
3 D0 tri_state Conversion data digital output, LSB; valid just after the CLK rising edge and high impedance when PD is low.
4 D1 tri_state Conversion data digital output bit 1; valid just after the CLK rising edge and high impedance when PD is low.
5 D2 tri_state Conversion data digital output bit 2; valid just after the CLK rising edge and high impedance when PD is low.
6 D3 tri_state Conversion data digital output bit 3; valid just after the CLK rising edge and high impedance when PD is low.
7 D4 tri_state Conversion data digital output bit 4; valid just after the CLK rising edge and high impedance when PD is low.
8 D5 tri_state Conversion data digital output bit 5; valid just after the CLK rising edge and high impedance when PD is low.
9 D6 tri_state Conversion data digital output bit 6; valid just after the CLK rising edge and high impedance when PD is low.
10 D7 tri_state Conversion data digital output, MSB; valid just after the CLK rising edge and high impedance when PD is low.
11 DVDD power_in Positive digital supply, +4.75 V to +5.25 V; share a common source with AVDD and bypass with 10 µF and 0.1 µF ceramic capacitors.
12 CLK input CMOS/TTL compatible clock input; VIN is sampled on the falling edge of CLK.
13 DVDD power_in Positive digital supply, +4.75 V to +5.25 V; share a common source with AVDD and bypass with 10 µF and 0.1 µF ceramic capacitors.
14 DVDD power_in Positive digital supply, +4.75 V to +5.25 V; share a common source with AVDD and bypass with 10 µF and 0.1 µF ceramic capacitors.
15 AVDD power_in Positive analog supply, +4.75 V to +5.25 V; share a common source with DVDD and bypass with 10 µF and 0.1 µF ceramic capacitors.
16 VRTS passive Reference top bias with internal pull-up resistor; short this pin to VRT to self-bias the reference ladder.
17 VRT input Analog input for the high (top) side of the reference ladder, range 1.0 V to VDD; it defines the VIN conversion range together with VRB and must be bypassed well.
18 AVDD power_in Positive analog supply, +4.75 V to +5.25 V; share a common source with DVDD and bypass with 10 µF and 0.1 µF ceramic capacitors.
19 VIN power_in Analog signal input; conversion range is VRB to VRT.
20 AVSS power_in Ground return for the analog supply; connect to DVSS close to the ADC1175-50 package.
21 AVSS power_in Ground return for the analog supply; connect to DVSS close to the ADC1175-50 package.
22 VRBS passive Reference bottom bias with internal pull-down resistor; short to VRB to self-bias the reference ladder, and bypass well unless grounded.
23 VRB input Analog input for the low (bottom) side of the reference ladder, nominal range 0.0 V to 4.0 V with optimized value 0.6 V; it defines the VIN conversion range together with VRT and must be bypassed well.
24 DVSS power_in Ground return for the digital supply; connect to AVSS close to the ADC1175-50.
