AD7277BRMZ

Analog Devices · Analog To Digital Converters (ADCs) · MSOP-8

AD7277BRMZ from Analog Devices, in a MSOP-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 VDD power_in Power supply input; the VDD range is 2.35 V to 3.6 V.
2 SDATA output Serial data output carrying the conversion result MSB first, with two leading zeros, 10 bits of data and four trailing zeros for the AD7277, clocked out on the falling edge of SCLK.
3 CS input Active-low chip select that initiates conversion and frames the serial data transfer.
4 NC unconnected No connect.
5 NC unconnected No connect.
6 SCLK input Serial clock logic input that clocks data out of the part and is also the clock source for the conversion process.
7 GND power_in Analog ground, the reference point for all circuitry; all analog input signals should be referred to this GND voltage.
8 VIN power_in Single-ended analog input channel with an input range of 0 V to VDD.

CAD (KiCad official)

  • Symbol: AD7277BRMZ
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: ad7277brmz-etched.step / ad7277brmz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ad7277brmz.step / ad7277brmz.glb are the bare package body.
