Dual op-amps for the low-
power consumption version
(380 µA with 2.5 MHz GBP)
Precision rail-to-rail input /
output 36 V, 6 MHz dual op-
amps
Description
The
TSB7191, TSB7191A, TSB7192
and the
TSB7192A
22 MHz bandwidth amplifier
feature rail-to-rail input and output, which is guaranteed to operate from +2.7 V to
+36 V single supply as well as from ±1.35 V to ±18 V dual supplies.
These amplifiers have the advantage of offering a large span of supply voltage and
an excellent input offset voltage of 300 µV maximum at 25 °C.
The combination of wide bandwidth, slew rate, low noise, rail-to-rail capability and
precision makes the
TSB7191, TSB7191A, TSB7192
and the
TSB7192A
useful in a
wide variety of applications such as: filters, power supply and motor control, actuator
driving, hall effect sensors and resistive transducers.

1. All voltage values, except the differential voltage are with respect to the network ground terminal.
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. The maximum input
voltage differential value may be extended to the condition that the input current is limited to ±10 mA. See Input pin voltage
range.
3. Input current must be limited by a resistor in series with the inputs when the input voltage is beyond the rails (see Input pin
voltage range).
