PRODUCT DESCRIPTION

PRODUCT HIGHLIGHTS

The BiFET series of precision, monolithic FET-input op amps

are fabricated with the most advanced BiFET and laser trim-

ming technologies. The AD542, AD544, AD547 series offers

bias currents significantly lower than currently available BiFET

devices, 25 pA max, warmed up.

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.

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.

3. Advanced laser wafer trimming techniques reduce offset volt-

age 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 en-

hance performance as a precision op amp.

The AD542 or AD547 is recommended for any operational am-

plifier application requiring excellent dc performance at low to

moderate cost. Precision instrument front ends requiring accu-

rate 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 imped-

ance buffer applications.

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.

The AD544 is recommended for any op amp applications re-

quiring 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.
