TA7522SG,TA7522FG

Dual Voltage Comparator

The TA7522SG is an easy-to-use IC incorporating two voltage

comparator circuits. Since one channel has an inverted-output

buffer, a CR oscillator can be easily built up.

The TA7522FG is in 8-pin dual inline package. The IC

incorporating two-circuit package. It does not contain an inverted

buffer output.

In addition, the TA7522SG/FG have a wide operating

temperature range that allows it to be used in a wide variety of

applications.

Features

• Two-circuit package

• High gain: 95dB (typ.)

• Single 3 V power supply for operation

• Inverted-output also available: TA7522SG only

• 0 V input causes action in the IC with a single power supply.

• Wide common-mode input range

• No latch-up

• Operating temperature range: −40 to 85°C

• Open-collector output

• SIP-9 pin (TA7522SG)

• SOP-8 pin (TA7522FG)

• Lead(Pb)-Free product
