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