The 20MHz Gain-Bandwidth (GBW) Product is achieved by using a proprietary and patent-pending output stage design. These characteristics allow excellent 16-bit settling times for driving 16-bit Analog-to-Digital converters (ADCs). Excellent ac characteristics, such as 20MHz GBW, 30V/ µs slew rate and 0.0003% THD+N make the OPA725 and OPA726 well-suited for communication, high-end audio, and active filter applications. With a bias current of less than 200pA, they are well-suited for use as transimpedance (I/V-conversion) amplifiers for monitoring optical power in ONET applications. The OPA725 and OPA726 op amps can be used in single-supply applications from 4V up to 12V, or dual-supply from ±2V to ±6V. The output swings to within 150mV of the rails, maximizing dynamic range. The shutdown versions (OPAx726) reduce the quiescent current to less than 6 µA and feature a reference pin for easy shutdown operation with standard CMOS logic in dual-supply applications. The OPA725 (single) is available in SOT23-5 and SO-8 packages, and the OPA2725 (dual) is available in MSOP-8 and SO-8 packages. The OPA726 (single with shutdown) is available in MSOP-8 and SO-8. The OPA2726 (dual with shutdown) is available in MSOP-10. All versions are specified for operation from −40 °C to +125°C. −V B V OUT +12V Enable OPA 726 λ 75 Ω OPA725 ADS8342 16−Bit ADC AIN Common 330pF V IN ±2.5V +5V −5V +5V −5V OPA725, OPA2725 OPA726, OPA2726 SBOS278B − SEPTEMBER 2003 − REVISED JANUARY 2004 Very Low Noise, High-Speed, 12V CMOS Operational Amplifier PRODUCTION DATA information is current as of publication date.
