Texas Instruments OPA313/OPA2313 Op Amps

Texas Instruments OPA313/OPA2313 Op Amps feature single-, dual-, and quad-channel op amps with rail-to-rail input and low noise (25nV/√Hz at 1 kHz). The low input bias current supports these amplifiers for use in applications with megaohm source impedances. These devices are optimized for operation at voltages as low as +1.8V (±0.9V) and up to +5.5V (±2.75V) and are specified over the extended temperature range of -40°C to +125°C. The OPA313 (single) is available in both SC70-5 and SOT23-5 packages. The OPA2313 (dual) is offered in SO-8, MSOP-8, and DFN-8 packages. The quad-channel OPA4313 is offered in a TSSOP-14 package.
