Op Amps Achieve -88 dBc SFDR At 5 MHz

Available in SOT23-6 packages, the MAX4285, 4288, 4387 and 4388 single-supply, 250-MHz operational amplifiers offer an SFDR of -88 dBc at 5 MHz. The op amps operate on supply voltages ranging from 2.85V to 6.5V single supplies or ±1.425V to ±3.25V dual supplies. Other features include a -3 dB bandwidth of 200 MHz, a slew rate of 350 V/µs, and an output current drive up to 100 mA. All of the devices have a low-power disable mode that reduces supply current and places the outputs in a high-impedance state. The devices come in six-pin SOT23, eight- and 14-pin SO, and eight- and 10-pin µMAX packages. Prices for the new operational amplifiers start from $0.89 each/1,000.
