资 源 简 介

The PGA202 is a monolithic instrumentaTIon ampli-fier with digitally controlled gains of 1, 10, 100, and1000. The PGA203 provides gains of 1, 2, 4, and 8.Both have TTL or CMOS-compaTIble inputs for easymicroprocessor interface. Both have FET inputs and anew transconductance circuitry that keeps the band-width nearly constant with gain. Gain and offsets arelaser trimmed to allow use without any external com-ponents. Both amplifiers are available in ceramic orplasTIc packages. The ceramic package is specifiedover the full industrial temperature range while theplasTIc package covers the commercial range.
