MAX951–MAX954

Ultra-Low-Power, Single-Supply

Op Amp + Comparator + Reference

Electrical Characteristics (continued)

(VDD = 2.8V to 7V for MAX951/MAX952, VDD = 2.4V to 7V for MAX953/MAX954, VSS = 0, VCM COMP = 0 for the MAX953/MAX954,

VCM OPAMP = 0, AMPOUT = (VDD + VSS)/2, COMPOUT = low, TA = TMIN to TMAX, typical values are at TA = +25°C, unless other-

wise noted.)

Note 1: Supply current is tested with COMPIN+ = (REF - 100mV) for MAX951/MAX952, and COMPIN+ = 0 for MAX953/MAX954.

Note 2: Input Offset Voltage is defined as the center of the input-referred hysteresis. VCM COMP = REF for MAX951/MAX952, and

VCM COMP = 0 for MAX953/MAX954.

Note 3: Trip Point is defined as the differential input voltage required to make the comparator output change. The difference

between upper and lower trip points is equal to the width of the input-referred hysteresis. VCM COMP = REF for MAX951/

MAX952, and VCM COMP = 0 for MAX953/MAX954.

Note 4: For MAX951/MAX952, input leakage current is measured for COMPIN- at the reference voltage. For MAX953/MAX954,

input leakage current is measured for both COMPIN+ and COMPIN- at VSS.

Note 5: Reference voltage is measured with respect to VSS. Contact factory for availability of a 3% accurate reference voltage in

the μMAX package.
