SINGLE-SUPPLY DUAL
OPERATIONAL AMPLIFIER
DESCRIPTION
The UTC M2904 consists of two independent, high gain,
internally frequency compensated operation amplifiers which
were designed specifically to operate from a single power
supplies is also possible and the low power supply current
drain is independent of the magnitude of the power supply
voltage.
FEATURES

*Operating Voltage: +3V~+32V
*Low Operating Current: 0.7mA (typ.)
*Slew Rate: 0.5V/s (typ.)
DIP-8
SOP-8
TSSOP-8
*Pb-free plating product number: M2904L

Note 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The device is guaranteed to meet performance specification within 0~+70
operating temperature range
and assured by design from -20~+85.
