ADA4927-2YCPZ-R7

Analog Devices · Differential OpAmps · LFCSP-24(4x4)

ADA4927-2YCPZ-R7 from Analog Devices, in a LFCSP-24(4x4). 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 -IN1 input Negative input summing node 1 of amplifier channel 1.
2 +FB1 output Positive output feedback connection 1 for the external feedback network.
3 +VS1 power_in Positive supply voltage 1 (pin 3 of two shorted positive supply pins for channel 1).
4 +VS1 power_in Positive supply voltage 1 (pin 4 of two shorted positive supply pins for channel 1).
5 -FB2 output Negative output feedback connection 2 for the external feedback network.
6 +IN2 input Positive input summing node 2 of amplifier channel 2.
7 -IN2 input Negative input summing node 2 of amplifier channel 2.
8 +FB2 output Positive output feedback connection 2 for the external feedback network.
9 +VS2 power_in Positive supply voltage 2 (pin 9 of two shorted positive supply pins for channel 2).
10 +VS2 power_in Positive supply voltage 2 (pin 10 of two shorted positive supply pins for channel 2).
11 VOCM2 input Output common-mode voltage 2 control pin; the datasheet notes it can be bypassed or left floating so the internal divider sets the output common mode near midsupply.
12 +OUT2 output Positive output 2 for load connection.
13 -OUT2 output Negative output 2 for load connection.
14 PD2 input Power-down pin 2 for amplifier channel 2.
15 -VS2 power_in Negative supply voltage 2 (pin 15 of two shorted negative supply pins for channel 2).
16 -VS2 power_in Negative supply voltage 2 (pin 16 of two shorted negative supply pins for channel 2).
17 VOCM1 input Output common-mode voltage 1 control pin; the datasheet notes it can be bypassed or left floating so the internal divider sets the output common mode near midsupply.
18 +OUT1 output Positive output 1 for load connection.
19 -OUT1 output Negative output 1 for load connection.
20 PD1 input Power-down pin 1 for amplifier channel 1.
21 -VS1 power_in Negative supply voltage 1 (pin 21 of two shorted negative supply pins for channel 1).
22 -VS1 power_in Negative supply voltage 1 (pin 22 of two shorted negative supply pins for channel 1).
23 -FB1 output Negative output feedback connection 1 for the external feedback network.
24 +IN1 input Positive input summing node 1 of amplifier channel 1.
25 EPAD passive Exposed pad; connect to any plane between and including +VS and -VS.
