ADS7823E from Texas Instruments, in a VSSOP-8. 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 | VREF | power_in | Reference input, 2.5V nominal; the reference may range from 50mV to VDD and sets the analog input range (0 to VREF). |
| 2 | AIN | input | Analog input sampled by the internal sample-and-hold, with a full-scale input range of 0 to VREF and about 25pF input capacitance. |
| 3 | A0 | input | Slave address bit 0; tie to VDD or digital ground, since the level at power-up sets device address bit A0. |
| 4 | GND | power_in | Ground reference; connect to a clean ground point, ideally a dedicated analog ground plane away from microcontroller ground. |
| 5 | A1 | input | Slave address bit 1; tie to VDD or digital ground, since the level at power-up sets device address bit A1. |
| 6 | SDA | bidirectional | I2C serial data line (open-drain); VIH min is 0.7 x VDD, VIL max is 0.3 x VDD, and VOL max is 0.4V at 3mA sink current. |
| 7 | SCL | input | I2C serial clock input (open-drain bus line) supporting standard (100kHz), fast (400kHz) and high-speed (3.4MHz) modes. |
| 8 | +VDD | power_in | Power supply, 3.3V nominal in the pin table; specified performance is 2.7V to 3.6V, and the 5V characterization uses 4.75V to 5.25V. |
