ADS1224IPWR

Texas Instruments · Analog To Digital Converters (ADC) · TSSOP-20

ADS1224IPWR from Texas Instruments, in a TSSOP-20. 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 DVDD power_in Digital power supply; supported voltage range 2.7V to 5.5V.
2 SCLK input Serial clock input for data output control; rising edge clocks out data MSB first.
3 CLK input System clock input; maximum frequency 8 MHz with 30% to 70% duty cycle.
4 DRDY/DOUT output Dual-function output: Data Ready indicator (low-active) or serial data output (MSB first, clocked by rising SCLK edge).
5 MUX0 input Multiplexer select input, bit 0; selects analog input channel in combination with MUX1.
6 MUX1 input Multiplexer select input, bit 1; selects analog input channel in combination with MUX0.
7 TEMPEN input Temperature sensor enable input; selects on-chip temperature sensor output through the multiplexer.
8 BUFEN input Input buffer enable input; enables high-impedance buffer (1.2 GΩ) for analog inputs when high.
9 AINP4 input Analog channel 4 positive input; differential input range ±5V relative to AINN4.
10 AINN4 input Analog channel 4 negative input; differential input range ±5V relative to AINP4.
11 AINP3 input Analog channel 3 positive input; differential input range ±5V relative to AINN3.
12 AINN3 input Analog channel 3 negative input; differential input range ±5V relative to AINP3.
13 AINP2 input Analog channel 2 positive input; differential input range ±5V relative to AINN2.
14 AINN2 input Analog channel 2 negative input; differential input range ±5V relative to AINP2.
15 AINP1 input Analog channel 1 positive input; differential input range ±5V relative to AINN1.
16 AINN1 input Analog channel 1 negative input; differential input range ±5V relative to AINP1.
17 GND power_in Analog and digital ground reference; common return for both analog and digital signal paths.
18 VREFN input Negative reference input; reference voltage (VREFP - VREFN) supported range 0.5V to 2.5V.
19 VREFP input Positive reference input; reference voltage (VREFP - VREFN) supported range 0.5V to 2.5V.
20 AVDD power_in Analog power supply; supported voltage range 2.7V to 5.5V.
