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 (maximum) and 0.05µV/°C of offset voltage drift (maximum) 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 multi-channel 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.
