The THS4021 and THS4022 are ultralow voltage

noise, high-speed voltage feedback amplifiers that

are ideal for applications requiring low voltage noise,

including

communication

and

imaging.

The

single-amplifier

THS4021

and

the

dual-amplifier

THS4022 offer very good ac performance with

350-MHz bandwidth, 470-V/

μs slew rate, and 40-ns

settling time (0.1%). The THS4021 and THS4022 are

stable at gains of 10 (–9) or greater. These amplifiers

have a high drive capability of 100 mA and draw only

7.8-mA

supply

current

per

channel.

With

total

harmonic distortion (THD) of –68 dBc at f = 1 MHz,

Figure 1.

the THS4021 and THS4022 are ideally suited for

applications requiring low distortion.
