Applications Information
Introduction
The ISL28156 is a single BiMOS rail-to-rail input, output
(RRIO) operational amplifier with an enable feature. The
ISL28256 is a dual version without the enable feature. Both
devices are designed to operate from single supply (2.4V to
5.0V) or dual supplies (±1.2V to ±2.5V) while drawing only
39
μ
A of supply current per amplifier. This combination of low
power and precision performance makes this device suitable
for a variety of low power applications including battery
powered systems.
Rail-to-Rail Input/Output
These devices feature bipolar inputs which have an input
common mode range that extends up to 0.5V beyond the v+
rail, and to within 10mV of the V- rail. The CMOS outputs
typically swing to within about 4mV of the supply rails with a
100k
Ω
load. The NMOS sinks current to swing the output in
the negative direction. The PMOS sources current to swing the
output in the positive direction.
Input Protection
All input terminals have internal ESD protection diodes to both
positive and negative supply rails, limiting the input voltage to
within one diode beyond the supply rails. They also contain
back-to-back diodes across the input terminals. For
applications where the input differential voltage is expected to
exceed 0.5V, external series resistors must be used to ensure
the input currents never exceed 5mA (Figure 35).
Enable/Disable Feature
The ISL28156 offers an EN pin that disables the device
when pulled up to at least 2.0V. In the disabled state (output
in a high impedance state), the part consumes typically
10μA. By disabling the part, multiple ISL28156 parts can be
connected together as a MUX. In this configuration, the
outputs are tied together in parallel and a channel can be
selected by the EN pin. The EN pin also has an internal pull
down. If left open, the EN pin will pull to the negative rail and
the device will be enabled by default.
