Product Description

PRODUCT DESCRIPTION
The AD846 is a monolithic, very high speed operational amplifier 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 offers significant advantages over conventional high speed operational amplifiers. It maintains a nearly constant 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.
