General Description The MAX9922/MAX9923 ultra-precision, high-side cur- rent-sense amplifiers feature ultra-low offset voltage (VOS) of 25µV (max) and laser-trimmed gain accuracy better than 0.5%. The combination of low VOS and high- gain accuracy allows precise current measurements even at very small sense voltages. The MAX9922/MAX9923 are capable of both unidirec- tional and bidirectional operation. For unidirectional operation, connect REF to GND. For bidirectional oper- ation, connect REF to VDD/2. The MAX9922 has adjustable gain set with two external resistors. The MAX9923T/MAX9923H/MAX9923F use an internal laser-trimmed resistor for fixed gain of 25V/V, 100V/V, and 250V/V, respectively. The devices operate from a +2.85V to +5.5V single supply, independent of the input common-mode voltage, and draw only 700µA operating supply current and less than 1µA in shutdown. The +1.9V to +28V current-sense input common-mode voltage range makes the MAX9922/MAX9923 ideal for current monitoring in applications where high accuracy, large common-mode measurement range, and mini- mum full-scale VSENSE voltage is critical. The MAX9922/MAX9923 use a spread-spectrum autozeroing technique that constantly measures and cancels the input offset voltage, eliminating drift over time and temperature, and the effect of 1/f noise. This, in conjunction with the indirect current-feedback tech- nique, achieves less than 25µV (max) offset voltage. The MAX9922/MAX9923 are available in a small 10-pin µMAX® package and are specified over the -40°C to +85°C extended temperature range.

All temperature limits are guaranteed by design. Note 2: VOS is measured in bidirectional mode with VREF = VDD/2. Note 3: Data sheet limits are guaranteed by design and bench characterization. Thermocouple effects preclude measurement of this parameter during production testing. Devices are screened during production testing to eliminate defective units. Note 4: VOS drift limits are guaranteed by design and bench characterization and are the average of drift from -40°C to +25°C and from +25°C to +85°C. Note 5: VRSB = VRS+ = 12V, VREF = VDD/2 for bipolar mode and VREF = 0V for unipolar mode. Gain accuracy and gain linearity are specified over a VSENSE range that keeps the output voltage 250mV away from the rails to achieve full accuracy. Output of the part is rail-to-rail, and goes to within 25mV of the rails, but accuracy is not maintained. Linear operation is not guaran- teed for VSENSE voltages > ±150mV. See the Typical Operating Characteristics section for plots of Input vs. Output. Note 6: This is the worst-case REF current needed to directly drive the bottom terminal of the gain setting resistors, at VDD = 3.3V, and VREF = VDD/2 while maintaining gain accuracy. An internal 1kΩ resistor (R1) is present in the MAX9923T/ MAX9923H/MAX9923F between the FB and REF pins, while in the MAX9922 the resistor is external and user selectable. A voltage identical to the VSENSE develops across this resistor. In all versions the REF input current is dependent on the mag- nitude and polarity of VSENSE, and in the MAX9922 it is dependent on the value of the external resistor as well. The input bias current for REF is typically 1pA in the MAX9922 since it connects to the gate of a MOS transistor. See the External Reference section for more details. Note 7: The range of VREF, VCM, and VSENSE may limit the output swing of the MAX9922 with adjustable gain set to less than 100V/V.
