M7240
3 1/2 LCD DISPLAY DRIVER,
A/D CONVERTERS
DESCRIPTION
The UTC M7240 is a low voltage power supply of three half A/D
conversion IC. With the M7240, the product can be assembled the
digital gauge outfit and digital multimeters with 3V batteries supply.
The M7240 has hare the following features: using the only two
batteries of 7V or a 3V lithium batteries can work for long time the
chip contains an internal clock generator which can be fine-tuned by
a resistor, slicing the band gap in design makes the benchmark
signals shift and temperature shift noise greatly improve, slicing the
negative power produced within the circuit design, the maximum
load current can reach to 2mA.
FEATURES
*Power Supply Voltage:2.5V ~ 6V
*external clock circuit within a resistor, used for clock
frequency fine-tuning
*Built-in close bandgap reference, low temperature drift
*High input impedance
*Low noise A/D converter
*Guaranteed zero reading with zero input.
*Has triggered buttons that keep and low voltage alarm function that
power
*Direct driver LCD display
