TIMING CHARACTERISTICS

(VDD = +2.7V to +3.3V (MAX5143/MAX5144), VDD = +4.5V to +5.5V (MAX5141/MAX5142), VREF = +2.5V, GND = 0, CMOS inputs,

TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Figure 1)

Note 1: Gain error tested at VREF = +2.0V, +2.5V, and +3.0V (MAX5143/MAX5144) or VREF = +2.0V, +2.5V, +3.0V, and +5.0V

(MAX5141/MAX5142).

Note 2: ROUT tolerance is typically ±20%.

Note 3: Min/max range guaranteed by gain-error test. Operation outside min/max limits will result in degraded performance.

Note 4: Reference input resistance is code dependent, minimum at 2155 hex in unipolar mode, 1155 hex in bipolar mode.

Note 5: Slew-rate value is measured from 10% to 90%.

Note 6: Guaranteed by design. Not production tested.

Note 7: Guaranteed by power-supply rejection test and Timing Characteristics.
