Evaluation Board Key Features
The ISL282xEVAL1Z is designed to enable the IC to operate
from a single supply, +2.4VDC to +5.5VDC or from split
supplies, ±1.2VDC to ±2.75V. The board is configured for a
dual op amp connected for differential input with a closed
loop gain of 10. A single external reference voltage (VREF)
pin and provisions for a user-selectable voltage divider-filter
are included.
Power Supplies
External power connections are made through the +V, -V,
VREF and Ground connections on the evaluation board.
+V and -V. For single supply operation, the -V and Ground
pins are tied together to the power supply negative terminal.
For split supplies +V and -V terminals connect to their
respective power supply terminals. De-coupling capacitors
C2 and C4 connect to their respective supplies through R16
and R31 0 Ω resistors. These resistors are 0 Ω but can be
changed by the user to provide additional power supply
filtering, or to reduce the voltage rate-of-rise to less than
±1V/μS. Two additional capacitors, C3 and C5 are
connected close to the part to filter out high frequency noise.
Anti-reverse diode D1 protects the circuit in the case of
accidental polarity reversal (see Figure 1).
Amplifier Configuration
The schematic of 1/2 of the op amp with the components
supplied is shown in Figure 2. The circuit implements a
differential input amp with a closed loop gain of 10. The
circuit can operate from a single supply or from dual
supplies. The VREF pin must be connected to ground to
