描述 Description

The LTC824x family of single, dual, and quadoperational amplifiers represents a new generation ofgeneral-purpose, low-power low-noise operational amplifiers.Featuring rail-to-rail output swing, lowquiescent current (250?μA/ch typical) combined with awide bandwidth of 1.5 MHz and very-low noise(14 nV/√Hz at 1 kHz) makes this family attractive fora variety of applications that require a good balancebetween cost and performance. The low input biascurrent supports those operational amplifiers to beused in applications with MΩ source impedances.

The robust design of the LTC824x provides ease-of-use to the circuit designer — a unity-gain stable,integrated RFI-EMI rejection filter, no phase reversalin overdrive condition, and high electrostaticdischarge (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 CMOSoperational amplifiers, in conjunction with the LTC826x?and LTC827x?provide a family ofbandwidth, noise, and power options to meet theneeds of a wide variety of applications.?
