Applications Information
Introduction
The ISL28156 is a BiMOS rail-to-rail input, output (RRIO)
operational amplifier with an enable feature. The device is
designed to operate from single supply (2.4V to 5.0V) or dual
supplies (±1.2V to ±2.5V) while drawing only 39A of supply
current. 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
This device features bi-polar 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 10A. 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.
The loading effects of the feedback resistors of the disabled
amplifier must be considered when multiple amplifier outputs
are connected together.
Current Limiting
This device has no internal current-limiting circuitry. If the
output is shorted, it is possible to exceed the Absolute
Maximum Rating for output current or power dissipation,
potentially resulting in the destruction of the device.
Power Dissipation
It is possible to exceed the +125°C maximum junction
temperatures under certain load and power-supply
conditions. It is therefore important to calculate the
maximum junction temperature (TJMAX) for all applications
to determine if power supply voltages, load conditions, or
package type need to be modified to remain in the safe
operating area. These parameters are related using
Equation 1:
where:
PDMAXTOTAL is the sum of the maximum power
dissipation of each amplifier in the package (PDMAX)
where:
TMAX = Maximum ambient temperature
θJA = Thermal resistance of the package
PDMAX = Maximum power dissipation of 1 amplifier
VS = Supply voltage
IMAX = Maximum supply current of 1 amplifier
VOUTMAX = Maximum output voltage swing of the
application
RL = Load resistance
