PRODUCT DESCRIPTION  
The AD846 is a monolithic, very high speed operational ampli-  
fier offering high performance. Although technically classed as a  
current-feedback or transimpedance amplifier, it may be used  
in much the same way as traditional op amps while providing  
significant performance benefits. Employing Analog Devices’  
junction isolated complementary bipolar (CB) process, the AD846  
achieves true “12-bit” (0.01%) precision on critical ac and dc  
parameters, a level of performance unmatched by amplifiers  
fabricated using either the dielectrically isolated (DI) or other  
bipolar processes.  
The AD846 is available in three performance grades. The AD846A  
and AD846B are rated over the industrial temperature range  
of –40°C to +85°C. The AD846S is rated over the full mili-  
tary temperature range of –55°C to +125°C and is available  
processed to MIL-STD-883B, Rev C.  
The AD846 is available in two types of 8-lead packages: plastic  
mini-DIP and hermetic cerdip. The AD846AR-16 is available in  
the 16-lead SOIC package. “A” and “S” grade chips are also  
available.  
The AD846 offers significant advantages over conventional  
high speed operational amplifiers. It maintains a nearly con-  
stant bandwidth and settling time to 0.01% over a wide range  
of closed-loop gains. This makes the AD846 ideal for amplifying  
the residue in multiple-pass analog-to-digital converters.  
PRODUCT HIGHLIGHTS  
1. The AD846 achieves settling times of 110 ns to 0.01%  
for gains of –1 to –10, with a 450 V/µs slew rate, while  
consuming only 5 mA of supply current.  
2. For closed-loop gains of –1 to –100, the high speed perfor-  
mance of the AD846 is achieved without sacrificing full 12-bit  
dc precision.  
Other advantages include: low input errors and high open-loop  
transresistance (200 MΩ) into a 500 Ω load, ensuring true  
12-bit dc accuracy for closed-loop gains from –1 to gains  
greater than –100. This combination of ac and dc perfor-  
mance makes the AD846 an excellent choice for buffering  
precision high speed DACs and flash ADCs.  
3. The AD846 is well suited to line driver and video buffer  
applications where the properties of low distortion and high  
slew rate are required.
