Texas Instruments · Analog To Digital Converters (ADC) · VSSOP-8
ADS7823EB 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 with 2.5V nominal; the converter operates with a reference from 50mV to VDD, and the full-scale input range is 0 to VREF. |
| 2 | AIN | input | Analog input; the full-scale input range is 0 V to VREF, and the internal sampling capacitor is typically 25pF. |
| 3 | A0 | input | Slave address bit 0; tie to VDD or digital ground, and the level is sampled at power-up to set the device address. |
| 4 | GND | power_in | Ground; the datasheet recommends a clean ground point, preferably the analog ground, away from microcontroller or DSP ground return. |
| 5 | A1 | input | Slave address bit 1; tie to VDD or digital ground, and the level is sampled at power-up to set the device address. |
| 6 | SDA | bidirectional | I2C serial data line on an open-drain I/O, supporting standard (100kHz), fast (400kHz) and high-speed (3.4MHz) modes. |
| 7 | SCL | input | I2C serial clock line on an open-drain input, driven by the master; the ADS7823 supports standard, fast and high-speed modes up to 3.4MHz. |
| 8 | +VDD | power_in | Power supply, 3.3V nominal; specified performance is 2.7V to 3.6V in the +2.7V characterization and 4.75V to 5.25V in the +5V characterization. |
