REF195GSZ-REEL7

Analog Devices · Voltage Reference · SOIC-8

REF195GSZ-REEL7 from Analog Devices, in a SOIC-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 TP unconnected Test pin reserved for in-package Zener zap trimming; the user should leave it unconnected.
2 VS power_in Supply input; the output remains regulated from supplies as low as 100 mV above the output voltage (low dropout).
3 SLEEP input Applying a low TTL or CMOS level enables sleep mode, which turns the output off and reduces supply current to less than 15 μA.
4 GND power_in Ground connection for the reference.
5 TP unconnected Test pin reserved for in-package Zener zap trimming; the user should leave it unconnected.
6 OUTPUT output Reference voltage output (5.00 V nominal for REF195); the part supplies up to 30 mA and has short-circuit protection.
7 NC unconnected No connect.
8 NC unconnected No connect.
