AD7401AYRWZ-RL

Analog Devices · ADCs/DACs - Special Purpose · SOIC-16-300mil

AD7401AYRWZ-RL from Analog Devices, in a SOIC-16-300mil. 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 VDD1 power_in Supply voltage for the isolated side, 4.5 V to 5.5 V, relative to GND1.
2 VIN+ power_in Positive analog input with a specified range of ±250 mV.
3 VIN− power_in Negative analog input, normally connected to GND1.
4 NC unconnected No connect.
5 NC unconnected No connect.
6 NC unconnected No connect.
7 VDD1/NC power_in Isolated-side supply voltage of 4.5 V to 5.5 V relative to GND1; the pin may be left floating but must not be tied to ground, as the device operates normally when supply is applied to pin 1.
8 GND1 power_in Ground reference point for all circuitry on the isolated side.
9 GND2 power_in Ground reference point for all circuitry on the nonisolated side.
10 NC unconnected No connect.
11 MDAT output Serial data output carrying the single-bit modulator stream, clocked out on the MCLKIN rising edge and valid on the following MCLKIN rising edge.
12 NC unconnected No connect.
13 MCLKIN input Master clock logic input, 20 MHz maximum; the modulator bit stream is valid on its rising edge.
14 VDD2 power_in Supply voltage for the nonisolated side, 3 V to 5.5 V, relative to GND2.
15 NC unconnected No connect.
16 GND2 power_in Ground reference point for all circuitry on the nonisolated side.
