Small, low-power, high-precision dual op amp optimised for low-voltage, single-supply operation

17-01-2018 | Texas Instruments | Power

Claimed to be the industry's smallest, low-power, high-precision dual Op Amp with >300kHz GBW, the Texas Instruments OPA2333P uses a proprietary auto-calibration technique to simultaneously produce very low offset voltage (10µV, maximum) with near-zero drift over time and temperature. This high-precision, miniature, low quiescent current amplifier gives high-impedance inputs that have a common-mode range 100mV beyond the rails, and rail-to-rail output that swings within 50mV of the rails. Single or dual supplies as low as 1.8V (±0.9V) and up to 5.5V (±2.75V) can be used. This device is optimised for low-voltage, single-supply operation. The device also features a specified maximum start-up time. Specified start-up time ensures high-precision performance after 500µs of powering the amplifier, allowing for reliable use in dynamic supply operation. The device offers excellent CMRR without the crossover associated with traditional complementary input stages. This results in superior performance for driving ADCs without degradation of differential linearity. The device is available in a 2mm × 2mm eight-pin WSON package and is specified for operation from –40C to 125C.
