Description

The TLVx333 series of CMOS operational amplifiers offer precision performance at a very competitive price. These devices are members of the zero-drift family of amplifiers that uses a proprietary auto-calibration technique to simultaneously provide low offset voltage (15 µV, max) and near-zero drift over time and temperature at only 28 µA (max) of quiescent current. The TLVx333 family features rail-to-rail input and output in addition to near-flat 1/f noise, making this amplifier ideal for many applications and much easier to design into a system. These devices are optimized for low-voltage operation as low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V).

The TLV333 (single version) is available in the SC70-5, SOT23-5, and SOIC-8 packages. The TLV2333 (dual version) is offered in VSSOP-8 and SOIC-8 packages. The TLV4333 is offered in the standard SOIC-14 and TSSOP-14 packages. All versions are specified for operation from –40°C to +125°C.
