Description
C2 PIN 1
M/A-COM’s AT-213-PIN is a 4-bit, 1 dB step digital
attenuator in a hermetically sealed ceramic 16-lead
surface mount package. The AT-213-PIN is ideally
suited for use where high accuracy, fast switching,
very low power consumption and low intermodulation products are required. Typical applications include dynamic range setting in a precision receiver
circuits and other gain/leveling control circuits. Environmental screening is available. Contact the factory for information.

Exceeding any one or combination of these limits may cause
permanent damage to this device.
M/A-COM does not recommend sustained operation near
these survivability limits.
Standard CMOS TTL interface, latch-up will occur if logic
signal is applied prior to power supply.
