Op amp delivers precision, low noise

Dallas, Tex. — Texas Instruments Inc. has introduced a single-supply operational amplifier with e-Trim precision and very low noise. The OPA376 combines a low offset voltage of 25 microamps (μA) (maximum) and a wide bandwidth of 5.5 MHz in micro-packages.

In addition, the OPA376 op amp offers low noise density of 7.5 nV/sq rt Hz and a quiescent current of 950 μA (maximum), which enable this device to meet requirements for both AC and DC specifications for filtering, data acquisition and single-supply processing systems. Applications include sensor and signal conditioning, wireless communications, medical instrumentation, handheld test equipment and consumer audio equipment.

The OPA376 device is also said to offer very low noise in relation to the quiescent current of less than 1 mA and excellent temperature drift characteristics of 1 μV/C (maximum). Dual and quad versions will be available in third quarter 2007. All versions are specified for operation over the temperature range of -40°C to +125°C and provide identical specifications.

Companion products of the OPA376 for portable medical and industrial applications include the OPA333, OPA340, ADS123x, MSP430 and REF50xx. For consumer audio applications, the OPA376 complements the OPA363/4, DAC557x, and audio Codec products.

Pricing: Suggested resale pricing for the OPA376 is $0.65 in quantities of 1,000. The dual version, OPA2376, will be priced at $1.00 and the quad version, OPA4376, will be priced at $1.40, both in quantities of 1,000.
Availability: The OPA376, offered in the micro-size SC70, SO-8 and SOT23-5, is available now. The dual-version OPA2376, in the MSOP-8 and SO-8 packages, and the quad version, OPA4376, in the TSSOP-14 package, will be available at the end of 3Q 2007.
