PRODUCT DESCRIPTION

The AD848 and AD849 are high speed, low power monolithic

operational amplifiers. The AD848 is internally compensated so

that it is stable for closed loop gains of 5 or greater. The AD849

is fully decompensated and is stable at gains greater than 24.

The AD848 and AD849 achieve their combination of fast ac

and good dc performance by utilizing Analog Devices’ junction

isolated complementary bipolar (CB) process. This process

enables these op amps to achieve their high speed while only

requiring 4.8 mA of current from the power supplies.

The AD848 and AD849 are members of Analog Devices’ family

of high speed op amps. This family includes, among others, the

AD847 which is unity gain stable, with a gain bandwidth of

50 MHz. For more demanding applications, the AD840,

AD841 and AD842 offer even greater precision and greater

output current drive.

The AD848 and AD849 have good dc performance. When

operating with

5 V supplies, they offer open loop gains of

13 V/mV (AD848 with a 500

Ω

load) and low input offset

voltage of 1 mV maximum. Common-mode rejection is a

minimum of 92 dB. Output voltage swing is

3 V even into

loads as low as 150

Ω.

NC = NO CONNECT

APPLICATIONS HIGHLIGHTS

1. The high slew rate and fast settling time of the AD848 and

AD849 make them ideal for video instrumentation circuitry,

low noise pre-amps and line drivers.

2. In order to meet the needs of both video and data acquisition

applications, the AD848 and AD849 are optimized and

tested for

5 V and

15 V power supply operation.

3. Both amplifiers offer full power bandwidth greater than

20 MHz (for 2 V p-p with

5 V supplies).

4. The AD848 and AD849 remain stable when driving any

capacitive load.

5. Laser wafer trimming reduces the input offset voltage to

1 mV maximum on all grades, thus eliminating the need for

external offset nulling in many applications.

6. The AD848 is an enhanced replacement for the LM6164

series and can function as a pin-for-pin replacement for

many high speed amplifiers such as the HA2520/2/5 and

EL2020 in applications where the gain is 5 or greater.
