TSV781ILT

The TSV78x is a unity-gain stable amplifier with a 30 MHz bandwidth. Its rail-to-rail input stage and 20 V/μs slew rate make it an ideal choice for low-side current sensing. The TSV78x operates from a 2.0 V to 5.5 V single supply and is fully specified with a 47 pF load, making it well-suited as an input buffer for ADCs. The TSV78x family offers rail-to-rail input and output, an excellent power-to-performance ratio, and a 30 MHz gain-bandwidth product while consuming only 3.3 mA from a 5 V supply. The device also features ultra-low input bias current, enabling connectivity with photodiodes and other sensors where current is the critical measured parameter. These characteristics make the TSV78x family an ideal choice for high-precision, high-bandwidth sensor interfaces.
