Product overview
Description
The TS185x (single, dual and quad) is operational amplifier able to operate with voltages as low as 1.8V. They feature both input and output rail-to-rail (1.71 @ VCC= 1.8V, RL= 2k
With a such low consumption and a sufficient GBP for many applications, this op-amp is very well-suited for any kind of battery-supplied and portable equipment applications.
The TS1851 is housed in the space-saving 5-pin SOT23-5 package which simplifies the board design (outside dimensions are 2.8mm x 2.9mm).
