TI Introduces Low-Noise Precision Amplifier for Single Supply Apps

(Product News, 6 Aug 2007)

Texas Instruments Incorporated (TI) has launched a single-supply operational amplifier with e-Trim precision and very low noise. The OPA376 combines low offset voltage of 25µA (max.) and wide bandwidth of 5.5MHz in micro-packages. 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 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 1µV/°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.
