The extremely low • SLEW RATE: 30V/µs offset (150 µV max) and drift (1.5µV/°C) are achieved • BIAS CURRENT: 500pA (max) by trimming the IC digitally after packaging to avoid the shift in parameters as a result of stresses during • LOW NOISE: 6nV/√Hz at 100kHz package assembly. To correct for offset drift, the • THD+N: 0.0003% at 1kHz OPA727 and OPA728 family is trimmed over • QUIESCENT CURRENT: 4.3mA/ch temperature. The devices feature very high CMRR and open-loop gain to minimize errors. • SUPPLY VOLTAGE: 4V to 12V • SHUTDOWN MODE (OPA728): 6µA Excellent ac characteristics, such as 20MHz GBW, 30V/ µs slew rate and 0.0003% THD+N make the OPA727 and OPA728 well-suited for communication, high-end audio, and active filter applications. With a • OPTICAL NETWORKING bias current of less than 500pA, they are well suited • TRANSIMPEDANCE AMPLIFIERS for use as transimpedance (I/V-conversion) • INTEGRATORS amplifiers for monitoring optical power in ONET applications. • ACTIVE FILTERS • A/D CONVERTER DRIVERS Optimized for single-supply operation up to 12V, the • I/V CONVERTER FOR DACs input common-mode range extends to GND for true single-supply functionality. The output swings to • HIGH PERFORMANCE AUDIO within 150mV of the rails, maximizing dynamic range. • PROCESS CONTROL The low quiescent current of 4.3mA makes it • TEST EQUIPMENT well-suited for use in battery-operated equipment. The OPA728 shutdown version reduces the quiescent current to typically 6 µA and features a reference pin for easy shutdown operation with FEATURES PRODUCT standard CMOS logic in dual-supply applications. 20MHz, 3mV, 4 µV/°C OPA725 (non-e-trim version of OPA727) For ease of use, the OPA727 and OPA728 op amp 20MHz, 3mV, 4 µV/°C, Shutdown OPA726 families are fully specified and tested over the supply (non-e-trim version of OPA728) range of 4V to 12V. The OPA727 (single) and OPA728 (single with shutdown) are available in MSOP-8 and DFN-8; the OPA2727 (dual) is available in DFN-8 and SO-8; and the quad version OPA4727 in TSSOP-14. All versions are specified for operation from –40 °C to +125°C.
