TLV2474-Q1 - Automotive 600-uA/Ch 2.8-MHz Rail-to-Rail Input/Output High-Drive Operational Amplifier

Updated : 2020-01-09 14:21:21
Description

The TLV247x is a family of CMOS rail-to-rail input/output operational amplifiers that establishes a new performance point for supply current versus ac performance. These devices consume just 600 µA/channel while offering 2.8 MHz of gain-bandwidth product. Along with increased ac performance, the amplifier provides high output drive capability, solving a major shortcoming of older micropower operational amplifiers. The TLV247x can swing to within 180 mV of each supply rail while driving a 10-mA load. For non-RRO applications, the TLV247x can supply ±35 mA at 500 mV off the rail. Both the inputs and outputs swing rail-to-rail for increased dynamic range in low-voltage applications. This performance makes the TLV247x family ideal for sensor interface, portable medical equipment, and other data acquisition circuits.

The family is fully specified at 3 V and 5 V across the automotive temperature range (–40°C to 125°C).
