# ADS1100A7IDBVT

**Texas Instruments** · Analog To Digital Converters (ADC) · SOT-23-6

ADS1100A7IDBVT from Texas Instruments, in a SOT-23-6. 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 | VIN+ | power_in | Positive differential analog input, which must stay between GND - 0.2 V and VDD + 0.2 V and is current-limited to 10 mA momentary per the datasheet's overvoltage guidance. |
| 2 | GND | power_in | Ground reference for the device; the VDD-to-GND rating is -0.3 V to +6 V and all other voltage limits are referenced to this pin. |
| 3 | SCL | input | I2C serial clock, input only, which the ADS1100 never drives and which can be driven to 6 V regardless of the supply voltage. |
| 4 | SDA | bidirectional | I2C serial data line, bidirectional, rated -0.5 V to 6 V to GND and can be driven to 6 V regardless of the supply voltage. |
| 5 | VDD | power_in | Single power supply input from 2.7 V to 5.5 V, which also serves as the ratiometric conversion reference; the absolute maximum VDD to GND is +6 V. |
| 6 | VIN- | power_in | Negative differential analog input, with the same GND - 0.2 V to VDD + 0.2 V limits as VIN+, and a full-scale input of ±VDD/PGA. |
