Webcast to address wireless power optimisation

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 two-cell battery applications.
These amplifiers are also excellent front-end devices for driving TI's low-voltage analogue-to-digital convertors 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 -40 to +125C, making this series well suited for automotive applications.
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 1000 piece quantities (suggested resale price).
The OPA2363 and OPA2364 are priced from $0.88 in 1000 piece quantities (suggested resale pricing).
Quad versions, the OPA4363 and OPA4364, will be available in 1Q03.
Both devices will be packaged in a TSSOP-14 and SO-14.
