TI launches low-power, zero-drift amplifiers for precision signal conditioning

08/20/2002


Tucson, AZ— Texas Instruments Inc. (TI) recently announced that its Burr-Brown product line now includes what it reports are the industry's lowest-power, zero-drift operational amplifiers. TI states these amplifiers are 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.

'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,' says Tadija Janjic, strategic marketing engineer of TI's high-performance amplifier products. 'By offering a three-times reduction in quiescent current, these devices enable customers to achieve higher precision designs while reducing power consumption.'

OPA334 and OPA335 op amps are available in micro-size SOT23 packages and feature low-quiescent current (300 uA); single-supply operation; and rail- to-rail output swing within 10 mV of the rails. The devices use auto-zeroing techniques to provide ultra-low offset voltage (1 uV typical) and near-zero drift over time and temperature (0.02 uV/C).

OPA334 family includes a shutdown mode allowing the OPA334 to be switched from normal operation to a standby current that is less than 1uA. OPA334 and OPA335 operate on single or dual supplies as low as +2.7 V (+/-1.35 V) and up to +5.5 V (+/-2.75 V). All versions are specified from -40 °C to +125 °C.
