AD737JRZ-R7

Analog Devices · RMS To DC Converters · SOIC-8

AD737JRZ-R7 from Analog Devices, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CC passive Coupling Capacitor connection for indirect DC coupling to Pin 2 (VIN). Also provides an alternative low-impedance input access to an internal 8 kΩ V-to-I resistor.
2 VIN input High-impedance (10^12 Ω) FET RMS signal input. Accepts RMS levels up to 200 mV (up to ~1 V with ±5 V supplies); peak transient input ±0.9 V at ±2.8/-3.2 V supplies, ±2.7 V at ±5 V.
3 POWER DOWN input Enable/disable control. When grounded or pulled low, the AD737 is enabled; when pulled high, the part enters power-saving standby mode (~25 µA typical supply current).
4 -VS power_in Negative power supply. Operating range -2.5 V to -16.5 V (dual-supply operation, ±2.5 V to ±16.5 V total).
5 CAV passive Averaging Capacitor connection. External CAV sets the RMS averaging time constant; typical value 33 µF (100 µF for improved crest-factor performance).
6 OUTPUT output DC output with negative-going polarity (output is negative with respect to COM). Output resistance typically 8 kΩ.
7 +VS power_in Positive power supply. Operating range +2.5 V to +16.5 V (dual-supply operation, ±2.5 V to ±16.5 V total). Typical supply current ~160 µA.
8 COM passive Common (analog ground reference). Output voltage is measured with respect to this pin.
