CHT-OPAL
DUAL PRECISION OPERATIONAL AMPLIFIER (225°C)
CHT-OPAL is an ultra high-precision, dual operational amplifier designed for applications that require very low offset and very low noise. Key features include single 5V nominal power supply and rail-to-rail inputs and outputs. Best-in-class precision on the full temperature range -55°C to +225°C encompasses low input offset (internally compensated) and low noise. The internal circuitry uses a clock that is internally generated. There is a spread-spectrum mode for this clock.
