DESCRIPTION

The PGA102 is a high speed, digitally programmable-

gain amplifier. CMOS/TTL-compatible inputs select

gains of 1, 10 or 100V/V. Each gain has an indepen-

dent input terminal, providing an input multiplexer

function.

On-chip metal film gain-set resistors are laser-trimmed

to provide excellent gain accuracy. High speed input

circuitry allows multiplexing of high speed signals.

The PGA102 is available in 16-pin plastic and ceramic

DIP packages. Commercial, industrial and military

temperature range models are available.
