Dual-Supply, Rail-to-Rail Op Amps
General Description
The MAX4493/MAX4494/MAX4495 single/dual/quad
general-purpose operational amplifiers are designed
for use in systems powered with dual supplies from
±2.25V to ±5.5V. These op amps provide a unity-gain
bandwidth of 5MHz with only 770µA of quiescent cur-
rent per amplifier. The wide input common-mode range
extends from 200mV beyond the negative rail to within
1.5V of the positive supply rail while the output swings
within 10mV (R_L = 100kΩ) of either rail.
These amplifiers have excellent (110dB) open-loop
gain with very low THD+N of 0.002% (f = 1kHz). The
single MAX4493 is available in a tiny 5-pin SC70 pack-
age and the dual MAX4494 is available in the space-
saving 8-pin SOT23. The quad MAX4495 is available in
both 14-pin TSSOP and 14-pin SO packages. All prod-
ucts are rated at the automotive temperature range of
-40°C to +125°C.
