TS271
CMOS Programmable
Low Power Single Operational Amplifier
■ Offset null capability (by external
compensation)
■ Dynamic characteristics adjustable ISET
■ Consumption current and dynamic
parameters are stable regarding the
voltage power supply variations
■ Output voltage can swing to ground
■ Very large ISET range
■ Stable and low offset voltage
■ Three input offset voltage selections
Description
The TS271 is a low cost, low power single
operational amplifier designed to operate with
single or dual supplies. This operational amplifier
uses the ST silicon gate CMOS process giving it
an excellent consumption-speed ratio. This
amplifier is ideally suited for low consumption
applications.
The power supply is externally programmable with
a resistor connected between pins 8 and 4. It
allows to choose the best consumption-speed
ratio and supply current can be minimized
according to the required speed. This device is
specified for the following ISET current values:
1.5µA, 25µA, 130µA.
This CMOS amplifier offers very high input
impedance and extremely low input currents. The
major advantage versus JFET devices is the very
low input currents drift with temperature see
Figure 8, Figure 19, Figure 30.
