AD547JH High Performance BiFET Operational Amplifier IC TO99 Package

AD547JH The BiFET series of precision, monolithic FET-input op amps are fabricated with the most advanced BiFET and laser trimming technologies. The AD547 series offers bias currents significantly lower than currently available BiFET devices, 25pA max, warmed up. In addition, the offset voltage is laser trimmed to less than 0.25 mV on the AD547L, which is achieved by utilizing Analog Devices’ exclusive laser wafer trimming (LWT) process. When combined with the AD547’s low offset drift (1 µV/°C), these features offer the user performance superior to existing BiFET op amps at low BiFET pricing. The AD547 is recommended for any operational amplifier application requiring excellent dc performance at low to moderate cost. Precision instrument front ends requiring accurate amplification of millivolt level signals from meg ohm source impedances will benefit from the device’s excellent combination of low offset voltage and drift, low bias current and low 1/f noise. High common-mode rejection (80 dB, min on the “K” and “L” grades) and high open-loop gain, even under heavy loading, ensures better than “12-bit” linearity in high impedance buffer applications. Devices in this series are available in four grades: the “J,” “K,” and “L” grades are specified over the 0°C to +70°C temperature range and the “S” grade over the –55°C to +125°C operating temperature range. All devices are offered in the hermetically sealed, TO-99 metal can package.
