50 mV Offset, 0.25 mV/5C,
35 mA, Zero-Drift
Operational Amplifier
The NCS325, NCS2325 and NCS4325 are CMOS operational
amplifiers providing precision performance. The Zero−Drift
architecture allows for continuous auto−calibration, which provides
very low offset, near−zero drift over time and temperature, and near
flat 1/f noise at only 35 mA (max) quiescent current. These benefits
make these devices ideal for precision DC applications. These op
amps provide rail−to−rail input and output performance and are
optimized for low voltage operation as low as 1.8 V and up to 5.5 V.
The single channel NCS325 is available in the space−saving SOT23−5
package. The dual channel NCS2325 is available in Micro8, SOIC−8,
and DFN−8. The quad channel NCS4325 is available in SOIC−14.

APPLICATIONS INFORMATION
INPUT VOLTAGE
EMI SUSCEPTIBILITY AND INPUT FILTERING
The NCS325, NCS2325 and NCS4325 have rail−to−rail
common mode input voltage range. Diodes between the
inputs and the supply rails keep the input voltage from
exceeding the rails.
Op amps have varying amounts of EMI susceptibility.
Semiconductor junctions can pick up and rectify EMI
signals, creating an EMI−induced voltage offset at the
output, adding another component to the total error. Input
pins are the most sensitive to EMI. The NCS325, NCS2325
and NCS4325 integrate a low−pass filter to decrease its
sensitivity to EMI.

APPLICATION CIRCUITS
+
Low−Side Current Sensing
The goal of low−side current sensing is to detect
over−current conditions or as a method of feedback control.
A sense resistor is placed in series with the load to ground.
Typically, the value of the sense resistor is less than 100 mW
to reduce power loss across the resistor. The op amp
amplifies the voltage drop across the sense resistor with a
gain set by external resistors R1, R2, R3, and R4 (where R1
= R2, R3 = R4). Precision resistors are required for high
accuracy, and the gain is set to utilize the full scale of the
ADC for the highest resolution.

Differential Amplifier for Bridged Circuits
produced is relatively small and needs to be amplified before
going into an ADC. Precision amplifiers are recommended
in these types of applications due to their high gain, low
noise, and low offset voltage.
Sensors to measure strain, pressure, and temperature are
often configured in a Wheatstone bridge circuit as shown in
Figure 24. In the measurement, the voltage change that is

the device pins. These techniques will reduce susceptibility
to electromagnetic interference (EMI). Thermoelectric
effects can create an additional temperature dependent
offset voltage at the input pins. To reduce these effects, use
metals with low thermoelectric−coefficients and prevent
temperature gradients from heat sources or cooling fans.
To ensure optimum device performance, it is important to
follow good PCB design practices. Place 0.1 mF decoupling
capacitors as close as possible to the supply pins. Keep traces
short, utilize a ground plane, choose surface−mount
components, and place components as close as possible to
