description
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-Ω 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.
