T he AD848 and AD849 are high speed, low power monolithic

operational amplifiers. T he AD848 is internally compensated so

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

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

T he AD848 and AD849 achieve their combination of fast ac

and good dc performance by utilizing Analog Devices’ junction

isolated complementary bipolar (CB) process. T his process

enables these op amps to achieve their high speed while only

requiring 4.8 mA of current from the power supplies.

1. T he 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

T he AD848 and AD849 are members of Analog Devices’ family

of high speed op amps. T his 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.

20 MHz (for 2 V p-p with ±5 V supplies).

4. T he 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.

T he 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.

6. T he 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.
