描述 Description

The LTC827x family of single, dual, and quad operational amplifiers represents a new generation of general-purpose, low-power low-noise operational amplifiers. Featuring rail-to-rail output swing, low quiescent current (1.4?mA/ch typical) combined with a wide bandwidth of 20 MHz and very-low noise (8 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 LTC827x provides 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 wide?supply?voltage range as low as 2.3 V (±1.15 V) and up to 24 V (±12 V). This latest addition of low noise CMOS operational amplifiers, in conjunction with the LTC824x?and LTC826x?provide a family of bandwidth, noise, and power options to meet the needs of a wide variety of applications.?
