Low power and no drift
puts op amps in handhelds
Texas Instruments reckons its OPA334 and OPA335 are the industry's lowest power zero-drift operational amplifiers
This makes them ideal for precision, power-sensitive applications such as handheld test equipment, medical instrumentation, temperature measurement, transducer signal amplification, electronic scales, automotive systems and battery-powered instruments. 'The OPA334 and OPA335 provide customers with the ultimate cost-effective solution for precision signal conditioning and reinforce TI's leadership position in the low-power, low-voltage market', said Tadija Janjic, strategic marketing engineer of TI's high-performance amplifier products.

'By offering a 3x reduction in quiescent current, these devices enable customers to achieve higher precision designs while reducing power consumption'.
The OPA334 and OPA335 op amps are available in micro-size SOT23 packages and feature low quiescent current (300uA), single supply operation and rail-to-rail output swing within 10mV of the rails.
The devices use auto-zeroing techniques to provide ultra low offset voltage (1uV typical) and near zero drift over time and temperature (0.02uV/C).
The OPA334 family includes a shutdown mode allowing the OPA334 to be switched from normal operation to a standby current that is less than 1uA.
The OPA334 and OPA335 operate on single or dual supplies as low as +2.7V (+/-1.35V) and up to +5.5V (+/-2.75V).
All versions are specified from -40 to +125C.
The OPA334 (single version with shutdown) comes in an SOT23-6.
The OPA335 (single without shutdown) is packaged in an SOT23-5 and SO-8.
The OPA2334 (dual with shutdown) comes in an MSOP-10.
The OPA2335 (dual without shutdown) is available in an MSOP-8 and SO-8.
The OPA334 and OPA335 are priced from $0.95 in 1000-piece quantities (suggested resale price).
The OPA2334 and OPA2335 are priced from $1.50 in 1000-piece quantities (suggested resale pricing).
