Operational amplifiers promise near-zero
drift
A new family of zero-drift operational amplifiers are ideal for demanding applications in medical instrumentation, temperature measurement, test equipment, security and consumer systems.
Providing an unmatched combination of precision, micropower and miniature packaging, Texas Instruments has a new family of zero-drift operational amplifiers Featuring ultralow offset (2mV), ultralow quiescent current (17mA), operation down to 1.8V and SC70 or SOT23 packages, the OPA333 is ideal for demanding applications in medical instrumentation, temperature measurement, test equipment, security and consumer systems

Reference design for wireless optical comms
A new technology from Texas Instruments dramatically cuts the cost and complexity of bringing the high-speed datarates of optical networking to end users.
"Texas Instruments has leveraged its expertise in analogue signal conditioning and process technology to deliver an ideal precision amplifier solution", said Gregg Lowe, Senior Vice President of TI's High-Performance Analogue Business.
"The OPA333 will serve as a key building-block component in advanced, next-generation applications that demand an unmatched combination of precision, low power, low operating voltage and miniature packages".
Fabricated using TI's high-performance, precision mixed-signal CMOS technology, the OPA333 uses auto-zeroing techniques to simultaneously provide very low offset voltage and near-zero drift over time and temperature.
The device offers high-impedance inputs that have a common-mode range 100mV beyond both rails and rail-to-rail output that swings within 100mV of the rail.
Single or dual supplies as low as 1.8V and up to 5.5V may be used.
The OPA333 features excellent CMRR (common-mode rejection ratio) without the crossover errors associated with traditional complementary input stages.
This design results in superior performance for driving analogue-to-digital convertors (ADCs) without degradation of differential linearity.
The OPA333 family is available now from TI and its authorised distributors.
The OPA333 (single version) is packaged in the SC70, SOT23-5 and SO-8, and is priced at $0.95 in 1000 piece quantities (suggested resale pricing).
The OPA2333 (dual version) is offered in 3 x 3mm DFN and SO-8 packages, and is priced at $1.50 in 1000 piece quantities.
All versions are specified for operation from -40 to +125C.
