# AD736ARZ-R7

**Analog Devices** · RMS To DC Converters · SOIC-8

AD736ARZ-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 pin. If dc coupling is desired at Pin 2, connect a coupling capacitor to this pin. If the coupling at Pin 2 is ac, connect this pin to ground. Note that this pin is also an input, with an input impedance of 8 kΩ, useful for applications with high input voltages and low supply voltages. |
| 2 | VIN | input | High impedance input pin (10^12 Ω FET input). Primary signal input to the RMS converter's full-wave rectifier front end. |
| 3 | CF | passive | Auxiliary low-pass filter capacitor node. Connect an auxiliary low-pass filter capacitor from the OUTPUT pin to this pin to reduce output ripple. |
| 4 | -VS | power_in | Negative supply voltage if dual supplies are used, or ground if connected to a single-supply source. Supply range -3.2 V to -16.5 V (dual supply) or 0 V (single supply). |
| 5 | CAV | passive | Averaging capacitor connection. Connect the RMS averaging capacitor here; its value sets low-frequency accuracy and settling time. |
| 6 | OUTPUT | output | DC output voltage from the buffered output amplifier. Provides the true-rms / average / absolute-value result. Output swing typically 0 V to 3.8 V at ±5 V supplies, 2 mA drive. |
| 7 | +VS | power_in | Positive supply voltage. +2.8 V to +16.5 V. Quiescent current 200 µA max. |
| 8 | COM | passive | Common (analog signal ground return) pin for the input and output signal paths. |
