Baseband Differential Input(IN+/-):.
MAX4209 indirect current-feedback instrumentation amplifier. The A and B blocks in Figure 2 are twotransconductance amplifiers that generate output currents from their differential input voltages and reject the common-mode input signals.
The fully differential inputs allow an input swing of±VREF.
Consequently, with a±1% resistance change, the fail-safe differential input could change from -80% to +68%.
High-speed differential inputs: Quadrature motion encoder support up to 5 MHz.
A two-point measurementmethod is employed in which two known values of a differential input voltage(load currents) are applied to the current-sense amplifier.
In audio block, a differential input circuit, audio LPF and 0dB/-6dB gain amplifier are integrated eliminating the needs for external LPF for audio outputs.
The DS90LV032A accepts low voltage(350 mV typical) differential input signals and translates them to 3V CMOS output levels.

The amplifier has differential inputs and an internal fully differential design.
Simple current source for low-cost and low-current applications. The output current, IO,is approximately equal to the differential input voltage, VIN+- VIN-, divided by R1, as shown in the following derivation.
Each amplifier features differential inputs and outputs and a total gain range of typically 50dB.
Ignoring the sensor voltage noise and the AD8629 current noise, a 1 mV p-p signal output from the thermopile yields a signal-to-noise ratio(SNR) of:One of the thermopiles is connected as the pseudo differential input to the ADuCM360 ADC1/ADC3 pair, and the second is connected to the ADC2/ ADC3 pair.
The MAX9115 accepts an LVDS differential input and translates it to an LVTTL/LVCMOS output.
Receiver input signals between +100mV and -100mV ensure that the receiver switches properly, because the input thresholds for differential signals are less than 200mV. The data of Figure 5 applies only to an ideal receiver,which switches at a 0V differential input.
The MAX9130 accepts an LVDS differential input and translates it to an LVTTL/LVCMOS output.
The amplifier's referenceprovides a bias voltage corresponding to zero differential input, and the ADC reference provides the scale factor.
The MAX9759 utilizes fully differential input amplifiers, a full-bridged output, comprehensive click-and-pop suppression, and features four selectable gain settings 6dB, 12dB, 18dB, 24dB.
When the open-loop amplifier is within its specified IVR, the differential input signal(VIN+- VIN-) is 180 degrees out of phase with VDIFF.
This device offers three fully differential input channels that may be independently programmed with a gain between +1V/V and +128V/V. Furthermore, it can compensate an input-referred DC offset up to 117% of the selected full-scale range.
As a result,the voltage drops along the top two leads cancel each other, and the differential input voltage at the ADC will be the same as the voltage across the RTD.
In industrial applications, a differential input is required when measuring low-level signals from thermocouples, strain gages, and bridge-type pressure sensors to reject common-mode interference from motors, ac power lines, or other noise sources that inject noise into the analog inputs of the analog-to-digital converter ADCs.
In addition, the CHOP and CHOP' clocks are coupled to the differential input pins through parasitic capacitances associated with the switches.

The current sensor CQ3303 has a single ended output,but the ADC AK9235NK has a differential input, so a reference voltage is necessary. So, I made 2.5V from the 5V power supply with a resistor divider on the board, and attached it to the AINN pin after an op-amp buffer. Ideally, the ADC will output just the middle code at zero current input. .
Phase inversion is possible if: the amplifier inputs are not CMOS,the maximum differential input is VSY, and the data sheet does not claim immunity to phase inversion.
