FEATURES
● DIGITALLY PROGRAMMABLE GAINS:
DECADE MODEL—PGA202
GAINS OF 1, 10, 100, 1000
BINARY MODEL—PGA203
GAINS OF 1, 2, 4, 8
● LOW BIAS CURRENT: 50pA max
● FAST SETTLING: 2
µs to 0.01%
● LOW NON-LINEARITY: 0.012% max
● HIGH CMRR: 80dB min
● NEW TRANSCONDUCTANCE CIRCUITRY
● LOW COST
DESCRIPTION
The PGA202 is a monolithic instrumentation ampli-
fier with digitally controlled gains of 1, 10, 100, and
1000. The PGA203 provides gains of 1, 2, 4, and 8.
Both have TTL or CMOS-compatible inputs for easy
microprocessor interface. Both have FET inputs and a
new transconductance circuitry that keeps the band-
width nearly constant with gain. Gain and offsets are
laser trimmed to allow use without any external com-
ponents. Both amplifiers are available in ceramic or
plastic packages. The ceramic package is specified
over the full industrial temperature range while the
plastic package covers the commercial range.
