# AD7277AUJZ-500RL7

**Analog Devices** · Analog To Digital Converters (ADCs) · TSOT-6

AD7277AUJZ-500RL7 from Analog Devices, in a TSOT-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 | VDD | power_in | Power supply input with a VDD range of 2.35 V to 3.6 V. |
| 2 | GND | power_in | Analog ground reference point for all circuitry; all analog input signals should be referred to this GND voltage. |
| 3 | VIN | power_in | Single-ended analog input channel with an input range of 0 V to VDD. |
| 4 | SCLK | input | Serial clock logic input used for accessing data from the part and also as the clock source for the conversion process. |
| 5 | SDATA | output | Serial data logic output clocked out on the falling edge of SCLK, MSB first; for the AD7277 it is two leading zeros, 10 bits of conversion data and four trailing zeros. |
| 6 | CS | input | Active-low chip select logic input that initiates conversion and frames the serial data transfer. |
