Texas Instruments · ADCs/DACs - Special Purpose · SOIC-8-300mil

AMC1303E2520DWVR from Texas Instruments, in a SOIC-8-300mil. 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 AVDD power_in High-side (isolated) analog supply, 3.0 V to 5.5 V referenced to AGND; decouple per the power-supply recommendations.
2 AINP input Non-inverting analog input; for the ±250 mV device (AMC1303x25x, including AMC1303E2520) the linear full-scale differential input is ±250 mV within the rated common-mode range.
3 AINN input Inverting analog input, typically connected to the low side of the shunt resistor; linear operation requires the differential input to stay within ±250 mV FSR.
4 AGND power_in High-side (analog) ground reference for the analog front end and AVDD domain.
5 DGND power_in Digital (controller-side) ground reference for DVDD and DOUT.
6 DOUT output Modulator bitstream output; on the AMC1303Ex this is the Manchester-coded output, which embeds the internal clock and has no separate CLKOUT pin.
7 DGND power_in On the AMC1303Ex this pin is the controller-side ground connection and must be tied to DGND because the CLKOUT function (which occupies pin 7 on the Mx variants) is not present.
8 DVDD power_in Digital (controller-side) supply, 2.7 V to 5.5 V; decouple per the power-supply recommendations.
