TLV4313 - Low-Power, RRIO, 750-uV Offset, 1-MHz Operational Amplifier for Cost-Sensitive Systems

The TLV313 family of single-, dual-, and quad-channel precision operational amplifierscombine low power consumption with good performance. This makes them suitable for a wide range ofapplications, such as wearables, utility metering, building automation, currency counters and more.The family features rail-to-rail input and output (RRIO) swings, low quiescent current (65 µA,typical), wide bandwidth (1 MHz) and very low noise (26 nV/√Hz at 1 kHz), making it attractive fora variety of battery-powered applications that require a good balance between cost and performance.Further, low-input-bias current enables these devices to be used in applications with megaohmsource impedances.

The robust design of the TLV313 devices provides ease-of-use to the circuit designer:unity-gain stability with capacitive loads of up to 150 pF, integrated RF/EMI rejection filter, nophase reversal in overdrive conditions, and high electrostatic discharge (ESD) protection (4-kVHBM).

The devices are optimized for operation at voltages as low as +1.8 V (±0.9 V) and up to+5.5 V (±2.75 V), and are specified over the extended temperature range of –40°C to +125°C.

The single-channel TLV313 device is available in both SC70-5 and SOT23-5 packages. Thedual-channel TLV2313 device is offered in SOIC-8 and VSSOP-8 packages, and the quad-channel TLV4313device is offered in a TSSOP-14 package.
