Power S upplies and Layout
The MAX492/MAX494/MAX495 operate from a single
2.7V to 6V power supply, or from dual supplies of
±1.35V to ±3V. For single-supply operation, bypass the
power supply with a 1μF capacitor in parallel with a
0.1μF ceramic capacitor. If operating from dual sup-
plies, bypass each supply to ground.
Good layout improves performance by decreasing the
amount of stray capacitance at the op amp’s inputs
and output. To decrease stray capacitance, minimize
both trace lengths and resistor leads and place exter-
nal components close to the op amp’s pins.
Rail-to-Rail Buffers
The Typical Operating Circuitshows a MAX495 gain-of-
two buffer driving the analog input to a MAX187 12-bit
ADC. Both devices run from a single 5V supply, and
the converter’s internal reference is 4.096V. The
MAX495’s typical input offset voltage is 200μV. This
results in an error at the ADC input of 400μV, or less
than half of one least significant bit (LSB). Without offset
trimming, the op amp contributes negligible error to the
conversion result.
