描述 Description

The TPA558x is the newest zero-drift amplifier with

maximum 20-μV low-offset voltage, low noise, and stable

high-frequency response. It incorporates proprietary and

patented design techniques to achieve excellent AC

performance with 15-MHz bandwidth, 4.9-V/μs slew rate,

and low distortion while drawing 1-mA quiescent current

per amplifier. The input common-mode voltage extends to

V–, and the output swings rail-to-rail. The amplifier can

be used as a plug-in replacement for many commercially

available op-amps to improve performance. Considering

the requirement of the low standby power in some

special applications, there is a shutdown function which is

TPA558xN series with only 7.5-μA shutdown current.

The TPA5581 and TPA5581U (1-ch veision) are offered in

the SOT23-5 and SC70-5 packages. The TPA5582 (2-ch

version) is available in the SOP-8, TSSOP-8, MSOP-8,

and DFN-8 packages. The TPA5581N (shutdown version)

is only offered in the SOT23-5 package. All versions

can be operated over the industrial temperature range of

−40°C to +125°C.
