PRODUCT DESCRIPTION
The AD711 is a high speed, precision monolithic operational
amplifier offering high performance at very modest prices. Its
very low offset voltage and offset voltage drift are the results of
advanced laser wafer trimming technology. These performance
benefits allow the user to easily upgrade existing designs that use
older precision BiFETs and, in many cases, bipolar op amps.
The AD711 is available in an 8-pin plastic mini-DIP, small out-
line, cerdip, TO-99 metal can, or in chip form.
PRODUCT HIGHLIGHTS
1. The AD711 offers excellent overall performance at very
competitive prices.
The superior ac and dc performance of this op amp makes it
suitable for active filter applications. With a slew rate of 16 V/µs
and a settling time of 1 µs to ±0.01%, the AD711 is ideal as a
buffer for 12-bit D/A and A/D Converters and as a high-speed
integrator. The settling time is unmatched by any similar IC
amplifier.
2. Analog Devices’ advanced processing technology and with
100% testing guarantees a low input offset voltage (0.25 mV
max, C grade, 2 mV max, J grade). Input offset voltage is
specified in the warmed-up condition. Analog Devices’ laser
wafer drift trimming process reduces input offset voltage
drifts to 3 µV/°C max on the AD711C.
The combination of excellent noise performance and low input
current also make the AD711 useful for photo diode preamps.
Common-mode rejection of 88 dB and open loop gain of
400 V/mV ensure 12-bit performance even in high-speed unity
gain buffer circuits.
3. Along with precision dc performance, the AD711 offers
excellent dynamic response. It settles to ±0.01% in 1 µs and
has a 100% tested minimum slew rate of 16 V/µs. Thus this
device is ideal for applications such as DAC and ADC
buffers which require a combination of superior ac and dc
performance.
The AD711 is pinned out in a standard op amp configuration
and is available in seven performance grades. The AD711J and
AD711K are rated over the commercial temperature range of
0°C to +70°C. The AD711A, AD711B and AD711C are rated
over the industrial temperature range of –40°C to +85°C. The
AD711S and AD711T are rated over the military temperature
range of –40°C to +125°C and are available processed to MIL-
STD-883B, Rev. C.
4. The AD711 has a guaranteed and tested maximum voltage
noise of 4 µV p-p, 0.1 to 10 Hz (AD711C).
5. Analog Devices’ well-matched, ion-implanted JFETs ensure
a guaranteed input bias current (at either input) of 25 pA
max (AD711C) and an input offset current of 10 pA max
(AD711C). Both input bias current and input offset current
are guaranteed in the warmed-up condition.
