AD637JRZ from Analog Devices, in a SOIC-16-300mil. 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 | NC | unconnected | No connect. Leave floating. |
| 2 | CAV | passive | Averaging capacitor connection. External capacitor sets the averaging time constant of the rms computation. |
| 3 | -VS | power_in | Negative supply voltage. Typically -3 V to -18 V. |
| 4 | COM | power_in | Common (analog ground) return. |
| 5 | NC | unconnected | No connect. Leave floating. |
| 6 | BUF IN | input | Buffer amplifier input. High impedance input to the on-chip buffer amplifier, typically used for post-filtering or as an input buffer. |
| 7 | dB OUT | output | Logarithmic (dB) output. Provides an output proportional to the log of the rms input, useful for wide dynamic range measurements. |
| 8 | BUF OUT | output | Buffer amplifier output. Low impedance output of the on-chip buffer amplifier. |
| 9 | NC | unconnected | No connect. Leave floating. |
| 10 | OUTPUT OFFSET | input | Output offset trim. Connect to a potentiometer between +VS and -VS to null the output offset voltage. |
| 11 | OUTPUT | output | RMS output. Provides the true rms (or mean square / absolute value depending on configuration) of the input signal. |
| 12 | SUMMING JUNCTION | input | Summing junction of the output amplifier. Access for external feedback and gain-setting resistors. |
| 13 | +VS | power_in | Positive supply voltage. Typically +3 V to +18 V. |
| 14 | dB COMMON | passive | dB output common. Reference/return pin for the dB output scaling network. |
| 15 | INPUT | input | Signal input to the RMS converter. Accepts AC signals up to the specified bandwidth; typically 1 V rms full scale. |
| 16 | NC | unconnected | No connect. Leave floating. |
