Description
Supply Voltage Pin. Operational range 2.7 V to 5.5 V.
Output Reference Control Pin. Internal reference mode enabled when pin is left open; otherwise, this
pin should be tied to VPOS. Do not ground this pin.
Signal Input Pin. Must be driven from an ac-coupled source. The low frequency real input impedance
is 225 Ω.
Power-Down Pin. For the device to operate as a detector, it needs a logical low input (less than
100 mV). When a logic high (greater than V
current goes to nearly zero (ground and internal reference mode less than 1 µA, supply reference
mode V
Device Ground Pin.
By placing a capacitor between this pin and VPOS, the corner frequency of the modulation filter is
lowered. The on-chip filter is formed with 27 pF||2 kΩ for small input signals.
Output Pin. Near rail-to-rail voltage output with limited current drive capabilities. Expected load
>10 kΩ to ground.
Supply Reference Control Pin. To enable supply reference mode, this pin must be connected to VPOS;
otherwise, it should be connected to COMM (ground).
