Digital Attenuator, 31.5 dB, 6-Bit,

TTL Driver, DC-4.0 GHz

Features

Description

M/A-COM's AT90-1107 is a GaAs FET 6-bit digital

attenuator with integral TTL driver. Step size is 0.5 dB pro-

viding a 31.5 dB total attenuation range. This device is in an

FQFP-N plastic surface mount package. The AT90-1107 is

ideally suited for use where accuracy, fast speed, very low

power consumption and low costs are required.

supply designs without switching noise, use AT90-0107.

Electrical Specifications: T

1. During turn-on, the device requires an initial “Turn-on Current”. Once operational, Icc will drop to the specified levels.

2. The DC-DC converter is guaranteed to start in 100 µs as long as the power supplies can provide a minimum of 100 mA “Turn-

3. Logic “0” = 0.0 - 0.8 V, sink current is 20 µA maximum.

4. Logic “1” = 2.0 - 5.0 V, source current is 20 µA maximum.
