The TSV991/2/4 family of single, dual & quad operational amplifiers offers low voltage operation and rail-to-rail input and output. This family features an excellent speed/power consumption ratio, offering a 20MHz gain- bandwidth, stable for gain above 3 (100pF capacitive load), while consuming only 1.1mA max at 5V supply voltage. It also features an ultra- low input bias current. These characteristics make the TSV991/2/4 family ideal for sensor interfaces, battery-supplied and portable applications, as well as active filtering.

TSV321/TSV358/TSV324 are low voltage versions of LM358 and LM324 commodity operational amplifiers, capable of operating with voltage as low as 2.5V and featuring both I/O rail-to-rail.
