3 Description

The TLV888, TLV2888, and TLV4888 (TLVx888)

are wide-bandwidth, low noise, zero-drift operational

amplifiers (op amps). These op amps feature only

15μV of offset voltage (max) and 0.1μV/°C of offset

voltage drift (max) over a wide temperature range.

The TLVx888 feature very fast settling time due

in part to the wide gain bandwidth and very high

slew rate. The settling time is further enhanced in

multichannel systems by the proprietary MUX-friendly

input architecture.

The combination of high precision, fast settling, and

low noise make the TLVx888 an excellent choice

for a wide range of applications, including signal

measurement, precision instrumentation, and data

acquisition.

The TLVx888 are available in industry standard

packages as well as micro-size packages to fit in the

most space constrained applications. The devices are

specified for operation from –40°C to +125°C.
