TLV2772A-Q1

具有关断功能的汽车类 2.7V 高转换率轨到轨输出运算放大器

The TLV277x CMOS operational amplifier family combines high slew rate and bandwidth, rail-to-rail output swing, high output drive, and excellent dc-precision. The device provides 10.5 V/µs of slew rate and 5.1 MHz of bandwidth while only consuming 1 mA of supply current per channel. This ac-performance is much higher than current competitive CMOS amplifiers. The rail-to-rail output swing and high output drive make these devices a good choice for driving the analog input or reference of analog-to-digital converters. These devices also have low distortion while driving a 600- load for use in telecom systems.

These amplifiers have a 360-µV input offset voltage, a 17 nV/Hz input noise voltage, and a 2-pA input bias current for measurement, medical, and industrial applications. The TLV277x family is also specified across an extended temperature range –40°C to 125°C, making it useful for automotive systems.

These devices operate from a 2.5-V to 5.5-V single supply voltage and are characterized at 2.7 V and 5 V. The single-supply operation and low power consumption make these devices a good solution for portable applications. The following table lists the packages available.
