Texas Instruments' OPAx316 family of single, dual, and quad operational amplifiers represents a new generation of general-purpose, low-power operational amplifiers. Featuring rail-to-rail input and output swings, low quiescent current (400 µA/ch typical) combined with a wide bandwidth of 10 MHz and very low noise (11 nV/√Hz at 1 kHz) make this family attractive for a variety of applications that require a good balance between cost and performance. The low input bias current supports those operational amplifiers to be used in applications with MΩ source impedances.

The robust design of the OPAx316 - a unity-gain stable, integrated RFI-EMI rejection filter, no phase reversal in overdrive condition, and high electrostatic discharge (ESD) protection (4 kV HBM) - provide ease-of-use to the circuit designer.

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). This latest addition of low-voltage CMOS operational amplifiers, in conjunction with the OPAx313 and OPAx314, provide a family of bandwidth, noise, and power options to meet the needs of a wide variety of applications.
