PRODUCT DESCRIPTION
PRODUCT HIGHLIGHTS
The BiFET series of precision, monolithic FET-input op amps are fabricated with the most advanced BiFET and laser trimming technologies. The AD542, AD544, AD547 series offers bias currents significantly lower than currently available BiFET devices, 25 pA 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 AD542 or 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 megohm 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. The AD544 is recommended for any op amp applications requiring excellent ac and dc performance at low cost. The 2 MHz bandwidth and low offset of the AD544 make it the first choice as an output amplifier for current output D/A converters, such as the AD7541, 12-bit CMOS DAC. 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.
1. Improved bipolar and JFET processing results in the lowest bias current available in a monolithic FET op amp. 2. Analog Devices, unlike some manufacturers, specifies each device for the maximum bias current at either input in the warmed-up condition, thus assuring the user that the device will meet its published specifications in actual use. 3. Advanced laser wafer trimming techniques reduce offset voltage drift to 1 µV/°C max and offset voltage to only 0.25 mV max on the AD547L. 4. Low voltage noise (2 µV p-p) and low offset voltage drift enhance performance as a precision op amp. 5. High slew rate (13 V/µs) and fast settling time to 0.01% (3 µs) make the AD544 ideal for D/A, A/D, sample-hold circuits and high speed integrators. 6. Low harmonic distortion (0.0025%) make the AD544 an ideal choice in audio applications. 7. Bare die are available for use in hybrid circuit applications.

NOTES 1 Open-Loop Gain is specified with V OS both nulled and unnulled. 2 Input Offset Voltage specifications are guaranteed after 5 minutes of operation at T A = +25°C. 3 Input Offset Voltage Drift is specified with the offset voltage unnulled. Nulling will induce an additional 3 µV/°C/mV of nulled offset. 4 Bias Current specifications are guaranteed at either input after 5 minutes of operation at T A = +25°C. For higher temperatures, the current doubles every 10°C. 5 Defined as the maximum safe voltage between inputs, such that neither exceeds ± 10 V from ground. Specifications subject to change without notice. Specifications shown in boldface are tested on all production units at final electrical test. Results from those tests are used to calculate outgoing quality levels. All min and max specifications are guaranteed, although only those shown in boldface are tested on all production units.
