# TLV2542IDR

**Texas Instruments** · Analog To Digital Converters (ADC) · SOIC-8

TLV2542IDR from Texas Instruments, in a SOIC-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 | CS | input | Chip select; high-to-low transition removes SDO from 3-state within maximum delay time. |
| 2 | VREF | power_in | External reference input for the analog-to-digital converter. |
| 3 | GND | power_in | Ground return for internal circuitry; all voltage measurements are with respect to GND. |
| 4 | AIN0 | input | Analog input channel 0 for dual-channel operation. |
| 5 | AIN1 | input | Analog input channel 1 for dual-channel operation. |
| 6 | VDD | power_in | Positive supply voltage from 2.7 V to 5.5 V. |
| 7 | SCLK | input | Serial clock input from host processor; receives SCLK with maximum frequency of 20 MHz. |
| 8 | SDO | output | 3-state serial output for A/D conversion result; MSB-first format; output data valid on falling SCLK edge. |
