Seiko Instruments Inc 

HIGH-PRECISION VOLTAGE DETECTOR

S-807 Series

2. Reference voltage circuit

The S-807 Series has 0.8 V typical reference voltage circuit as-

VREF (a high-stable reference voltage source) .

It features:

• Low power consumption

• Good temperature characteristic

3. Comparator

The comparator drives a differential amplifier with a current

consumption of only 0.5µA as shown in Figure 15.

It features:

• Good matching characteristics

• Wide operating voltage range

• Low offset voltage

4. Other characteristics

(1) Temperature characteristic of detection voltage

Because of the excellent temperature characteristic of the reference voltage circuit, the temperature characteristics of

the detection voltage are expressed by the following formula in the range of -30°C to +80°C.

-VDET × (±0.1) mV/°C typ.

-VREF

*-VREF is 0.65 V min., 0.8 V typ., 0.95 V max.
