ADS1230IPWR from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DVDD | power_in | Digital power supply, 2.7V to 5.3V |
| 2 | DGND | power_in | Digital ground reference |
| 3 | CLKIN | input | External clock input, typically 4.9152MHz with allowable frequency range 0.2 to 6 MHz; tie low to activate internal oscillator |
| 4 | GAIN | input | PGA gain select input: 0 selects gain of 64, 1 selects gain of 128 |
| 5 | CAP | passive | Gain amplifier bypass capacitor connection with internal 2kΩ resistor; use 0.1µF external capacitor for 720Hz low-pass filter corner frequency |
| 6 | CAP | passive | Gain amplifier bypass capacitor connection with internal 2kΩ resistor; use 0.1µF external capacitor for 720Hz low-pass filter corner frequency |
| 7 | AINP | input | Positive analog input for differential measurement; full-scale input range ±39mV at gain 64 or ±19.5mV at gain 128; protected with internal ESD diodes |
| 8 | AINN | input | Negative analog input for differential measurement; full-scale input range ±39mV at gain 64 or ±19.5mV at gain 128; protected with internal ESD diodes |
| 9 | REFN | input | Negative reference input; REFN must be within AGND - 0.1V to REFP - 1.5V, protected with internal ESD diodes |
| 10 | REFP | input | Positive reference input; REFP must be within REFN + 1.5V to AVDD + 0.1V, protected with internal ESD diodes |
| 11 | AGND | power_in | Analog ground reference |
| 12 | AVDD | power_in | Analog power supply, 2.7V to 5.3V |
| 13 | SPEED | input | Data rate select input: 0 selects 10SPS data rate with simultaneous 50Hz and 60Hz rejection, 1 selects 80SPS data rate |
| 14 | PDWN | input | Power-down input; holding this pin low powers down entire converter and resets ADC circuitry; must remain low for minimum 26µs pulse width |
| 15 | SCLK | input | Serial clock input; data clocked out on rising edge at maximum frequency 5MHz; also initiates offset calibration and standby modes; includes built-in hysteresis |
| 16 | DRDY/DOUT | output | Dual-purpose output: indicates valid data by going low, then outputs 20-bit conversion data MSB first on subsequent SCLK rising edges |
