The OPA376 combines low offset voltage of 25uA （max） and wide bandwidth of 5.5MHz in micro-packages. In addition, the device offers low noise density of 7.5nV/sq rt Hz and quiescent current of 950uA （max）. 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. （See www.ti.com/opa376-pr.） Modern CMOS process technology with package level trim equates to ultra-low input offset voltage that minimizes signal errors and maximizes 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 （max）. 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 Codecs products. Availability and Packaging The OPA376 is available now from TI and its authorized distributors. It is offered in the micro-size SC70, SO-8 and SOT23-5 packages and is priced at $0.65 in 1,000-piece quantities （suggested resale pricing）. The dual version, OPA2376, will be available at the end of 3Q 2007 in the MSOP-8 and SO-8 packages and priced at $1.00 in 1,000-piece quantities. The quad version, OPA4376, will be available at the end of 3Q 2007 in the TSSOP-14 package and priced at $1.40 in 1,000-piece quantities. All versions are specified for operation from -40C to +125C and have identical specifications for maximum design flexibility. TI offers analog engineers a wide-ranging support infrastructure that includes training and seminars, design tools and utilities, technical documentation, evaluation modules, an online KnowledgeBase, a product information hotline and a comprehensive offering of samples that ship within 24 hours of request.
