Single-supply amplifiers are trimmed to precision

Op amps provide a balance of parameters required to meet both AC and DC specifications for filtering, data acquisition and single-supply processing systems.

Texas Instruments has introduced a single-supply operational amplifier with e-Trim precision and very low noise.

The OPA376 combines low offset voltage of 25uA (maximum) and wide bandwidth of 5.5MHz in microminiature packaging.

In addition, the device offers low noise density of 7.5nV/(rt)Hz and maximum quiescent current of 950uA.

These attributes provide a balance of parameters required to meet both AC and DC specifications for filtering, data acquisition and single-supply processing systems.

The device works well in sensor and signal conditioning, wireless communications, medical instrumentation, handheld test equipment and consumer audio equipment.

Modern CMOS process technology with package level trim equates to ultralow input offset voltage that minimises signal errors and maximises dynamic range.

Furthermore, this device has impressive low noise in relation to the quiescent current (less than 1mA) and excellent temperature drift characteristics of 1uV/C (maximum).

TI provides customers a state-of-the-art signal chain for precision applications.

Companion products of the OPA376 for portable medical and industrial applications include OPA333, OPA340, ADS123x, MSP430 and REF50xx.

For consumer audio applications, the OPA376 complements OPA363/4, DAC557x, and audio codec products.

The OPA376 is available now from TI and its authorised distributors.

It is offered in SC70, SO-8 and SOT23-5 packages and is priced at US $0.65 in 1000-piece quantities (suggested resale pricing).

The dual version, OPA2376, will be available at the end of Q3 2007 in the MSOP-8 and SO-8 packages and priced at $1.00 in 1000-piece quantities.

The quad version, OPA4376, will be available at the end of Q3 2007 in the TSSOP-14 package and priced at $1.40 in 1000-piece quantities.

All versions are specified for operation from -40 to +125C and have identical specifications for maximum design flexibility.
