Product Summary
The PGA203KP is a digitally controlled programmable gain instrumentation amplifier with digitally controlled gains of 1, 10, 100, and 1000. The PGA203KP provides gains of 1, 2, 4, and 8. Both have TTL or CMOS compatible inputs for easy microprocessor interface. The PGA203KP has FET inputs and a new transconductance circuitry that keeps the bandwidth nearly constant with gain. Gain and offsets are laser trimmed to allow use without any external components. The PGA203KP is 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.
