Input/Output Rail-to-Rail Low Power Operational Amplifier
■ Rail-to-rail input common-mode voltage range
■ Rail-to-rail output voltage swing
■ Operating from 2.7V to 12V
■ High-speed (3MHz, 1V/µs)
■ Low consumption (0.9mA @ 3V)
■ Supply voltage rejection ratio: 80dB
■ Latch-up immunity
■ Available in SOT23-5 micropackage
Description
The TS95x family are rail-to-rail BiCMOS
operational amplifiers optimized and fully
specified for 3V and 5V operation.
The TS951 is housed in the space-saving 5 pins
SOT23 package that makes it well suited for
battery-powered systems. This micropackage
simplifies the PC board design because of it’s
ability to be placed in tight spaces (outside
dimensions are: 2.8mm x 2.9mm)

1. All voltage values, except differential voltage are with respect to network ground terminal.
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. If Vid > ±1V,
the maximum input current must not exceed ±1mA. In this case (Vid > ±1V) an input serie resistor must be
added to limit input current.
3. Do not exceed 14V.
4. Short-circuits can cause excessive heating and destructive dissipation.
5. Human body model, 100pF discharged through a 1.5kΩ resistor into pin of device.
6. Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC with
no external series resistor (internal resistor < 5Ω), into pin to pin of device.
