DUAL OPERATIONAL AMPLIFIER
DESCRIPTION
The UTC M2115 is a low operating Voltage(1.0V
min.) and low saturation output voltage(2.0V p-p at
supply voltage 2.5V) operational amplifier. It is
applicable to handy type CD,radio cassete CD, and
portable DAT, that are digital audio apparatus which
require the 5V single supply operation and high output
voltage. The UTC M2115 is improved version of the UTC
M2100 about BIAS-CIRCUIT. So the UTC M2115 is low
saturation compared to the UTC M2100 under the
condition of low supply voltage(< 2.5V).The UTC
M2115 is stable about the oscillation compared to the
UTC M2100 under the condition of V+/V- >2.5V.
FEATURES
* Operating Voltage: 1V ~7V
*Low Saturation Output Voltage: 2.0Vp-p@V+=2.5V
*Slew Rate: 4V/s (typ.)
*Unity Gain Bandwidth: 12MHz (typ.)

Note 1:Applied circuit voltage gain is desired to be operated within the range of 3dB to 30dB.
Note 2:Special care being required for input common mode voltage range and the oscillation due to the capacitive
load when operating follower.
