TS321

Low-power single operational amplifier

Datasheet − production data

Features

■ Large output voltage swing

– 0 to 3.5 V min. (V

= 5 V)

■ Low supply current: 500 µA

■ Low input bias current: 20 nA

■ Low input offset voltage

– 2 mV max. for TS321A

– 4 mV max. for TS321

■ Wide power supply range

– Single supply: +3 to +30 V

– Dual supplies: ±1.5 to ±15 V

■ Stable with high capacitive loads

Description

The TS321 device is intended for cost-sensitive

applications where space saving is of great

importance. This bipolar op amp offers the

benefits of a reduced component size (SOT23-5

package) with specifications that match (or are

better than) industry standard devices (such as

the popular LM358A, LM324 devices, and as

such). The TS321 device has an input common

mode range (V

icm

) that includes ground and

therefore can be employed in single supply

applications.

Macromodel TS321 4 Macromodel 4.1 Important note concerning this macromodel Note the following remarks before using the macromodel. ● All models are a trade-off between accuracy and complexity (that is, simulation time). ● Macromodels are not a substitute to breadboarding; rather, they confirm the validity of a design approach and help to select surrounding component values.
