Description

The M51209P is a quad (four independent) comparator and operates over a wide voltage range from a single supply voltage. Especially the M51209P has superiority as to characteristics of input current ( input resistance ) and fits to wide ranged application, for example CR Timer, oscillator, etc.

Features

1. Low input current ( high input resistance ) : 20 nA(typ.)

2. Wide supply voltage range : 2.5 V ~ 28 V

3. Low dissipation current : 6.8 mA(typ.)

4. Capable of driving a relay or a lamp directly : 200 mA(max.)

5. Includes voltage surge absorbing zener diodes

6. High output breakdown voltage : 30 V(max.)

7. Low output voltage(Isink=60mA) : 0.2 V(typ.)

8. Low input offset voltage : 2 mV(typ.)

Pinouts:

Applications:

1. Voltage comparator, sequential timer, pulse generator

2. Analog / digital converter, time delay circuit

Description

The MAX971 Thru MAX974 and MAX981 Thru MAX984 single/dual/quad low-voltage comparators feature the lowest power consumption available. These micropower devices draw less than 4µA supply current over temperature (MAX971 / MAX972 / MAX981 / MAX982), and include an internal 1.182V ±1% (MAX971 / MAX973 / MAX974) or ±2% (MAX981 thru MAX984) voltage reference and programmable hysteresis.

Ideal for 3V or 5V single-supply applications, these devices operate from a single 2.5V to 11V supply (or ±1.25V to ±5.5V dual supplies), and each comparator’s input voltage ranges from the negative supply rail to within 1.3V of the positive supply. The single MAX971 / MAX981 and the dual MAX973 / MAX982 / MAX983 provide a unique, simple method for adding hysteresis without feedback or complicated equations, simply by using the HYST pin plus two resistors.
