Mnemonic

Description

1

CC

Coupling Capacitor Connection for Indirect DC Coupling to Pin 2. In addition, CC is an alternative low

impedance input access to an 8 kΩ voltage to current (V to I) resistor.

2

VIN

RMS Input to FET.

3

POWER DOWN

Disables the AD737. When Pin 3 is grounded or pulled low, the AD737 is enabled; when Pin 3 is pulled high, it

changes to power saving mode.

4

–VS

Negative Power Supply.

5

CAV

Averaging Capacitor Connection.

6

OUTPUT

DC Output (Negative Going Polarity).

7

+VS

Positive Power Supply.
