TI's Next-Generation Precision, Low-Voltage Op Amps Target Portable Applications

Dec 4, 2002

TUCSON, Ariz. (Dec. 4, 2002) -- Texas Instruments (TI) Incorporated (NYSE:TXN) today announced a series of precision 1.8V operational amplifiers from the company´s Burr-Brown product line which are optimized for battery-powered applications such as sensor amplification, signal conditioning, data acquisition, handheld instrumentation, portable audio and portable medical. (See amplifier.ti.com/sc02245).


The OPA363 and OPA364 op amps feature low offset (500uV max) and low quiescent current (750uA/ch max). Rail-to-rail input without crossover between input stages reduces distortion and improves CMRR (100dB) over the entire input range.
"The OPA363 and OPA364 provide designers with a cost-effective series of precision op amps which extends TI's industry-leading portfolio of 1.8V to 5.5V amplifiers," said Tadija Janjic, strategic marketing engineer of TI's high-performance amplifier products. "Stellar performance at 1.8V makes the OPA363 and OPA364 ideal for 2-cell battery applications. These amplifiers are also excellent front-end devices for driving TI's low-voltage analog-to-digital converters such as the ADS8324 and ADS8325."
Other features include micro-size SOT23 packages, rail-to-rail output swing within 5mV of the rails, high bandwidth (7MHz) and high slew rate (5V/us). The OPA363 family includes a shutdown mode which reduces power consumption to 0.9uA. All versions are specified from -40C to +125C, making this series well suited for automotive applications.

Availability, Packaging and Pricing

The OPA363 (single version with shutdown) comes in a SOT23-6 and SO-8. The OPA364 (single without shutdown) is packaged in a SOT23-5 and SO-8. The OPA2363 (dual with shutdown) comes in an MSOP-10 and the OPA2364 (dual without shutdown) is available in an MSOP-8 and SO-8.

The

OPA363

and

OPA364

are priced from $0.55 in 1,000 piece quantities (suggested resale price). The

OPA2363

and

OPA2364
