8 Detailed Description

8.1 Overview

The TLVx333 series of low-cost operational amplifiers are unity-gain stable and free from unexpected output

phase reversal. These devices use a proprietary auto-calibration technique to provide low offset voltage and very

low drift over time and temperature. The TLVx333 family also offers rail-to-rail input and output and near-flat 1/f

noise. These features make this series of op amps ideal for many applications and much easier to design into a

wide variety of systems.

8.3 Feature Description

The TLV333, TLV2333, and TLV4333 are unity-gain stable, precision operational amplifiers free from unexpected

output phase reversal. The use of proprietary zero-drift circuitry gives the benefit of low input offset voltage over

time and temperature, as well as lowering the 1/f noise component. As a result of the high PSRR, these devices

work well in applications that run directly from battery power without regulation. The TLV333 family is optimized

for low-voltage, single-supply operation. These miniature, high-precision, low quiescent current amplifiers offer

high-impedance inputs that have a common-mode range 100 mV beyond the supplies and a rail-to-rail output

that swings within 100 mV of the supplies under normal test conditions. The TLV333 series are precision

amplifiers for cost-sensitive applications.

8.3.1 Operating Voltage

(±0.9 V) up to 5.5 V (±2.75 V). Supply voltages greater than 7 V can permanently damage the device; see the

Absolute Maximum Ratings table. Key parameters that vary over the supply voltage or temperature range are

listed in the Typical Characteristics section.
