The AD628 is a precision difference amplifier that combines  
excellent dc performance with high common-mode rejection  
over a wide range of frequencies. When used to scale high  
voltages, it allows simple conversion of standard control  
voltages or currents for use with single-supply ADCs. A  
wideband feedback loop minimizes distortion effects due to  
capacitor charging of Σ-Δ ADCs.

Figure 2. CMRR vs. Frequency of the AD628  
A reference pin (VREF) provides a dc offset for converting bipolar  
to single-sided signals. The AD628 converts +5 V, +10 V, 5 V,  
10 V, and 4 to 20 mA input signals to a single-ended output  
within the input range of single-supply ADCs.  
A precision 10 kΩ resistor connected to an external pin is  
provided for either a low-pass filter or to attenuate large  
differential input signals. A single capacitor implements a low-  
pass filter. The AD628 operates from single and dual supplies  
and is available in an 8-lead SOIC_N or an 8-lead MSOP. It  
operates over the standard industrial temperature range of  
−40°C to +85°C.  
The AD628 has an input common mode and differential mode  
operating range of 120 V. The high common mode, input  
impedance makes the device well suited for high voltage  
measurements across a shunt resistor. The inverting input of  
the buffer amplifier is available for making a remote Kelvin  
connection.
