В® PGA103 Programmable Gain
AMPLIFIER
FEATURES DESCRIPTION в—Џ DIGITALLY PROGRAMABLE GAINS:
G=1, 10, 100V/V The PGA103 is a programmable-gain amplifier for
general purpose applications. Gains of 1, 10, or 100 are
digitally selected by two CMOS/TTL-compatible inputs. The PGA103 is ideal for systems that must
handle wide dynamic range signals. в—Џ CMOS/TTL-COMPATIBLE INPUTS
в—Џ LOW GAIN ERROR: В±0.05% max, G=10
● LOW OFFSET VOLTAGE DRIFT: 2µV/°C The PGA103’s high speed circuitry provides fast settling time, even at G=100 (8µs to 0.01%). Bandwidth
is 250kHz at G=100, yet quiescent current is only
2.6mA. It operates from В±4.5V to В±18V power
supplies. в—Џ LOW QUIESCENT CURRENT: 2.6mA
в—Џ LOW COST
в—Џ 8-PIN PLASTIC DIP, SO-8 PACKAGES The PGA103 is available in 8-pin plastic DIP and
SO-8 surface-mount packages, specified for the –40°C
to +85В°C temperature range. APPLICATIONS
