Analog Devices Inc. (Norwood, MA) announced the AD8021 high-speed amplifier, which utilizes the second-generation XFCB process to achieve a wide bandwidth of 200MHz and 190MHz, low noise of 2.1nV/rtHz and 2.1pA/rtHz, and a 16-bit distortion performance of 93dBc SFDR at 1MHz and 100dBc at 100kHz.
The device operates via supply voltages ranging from ±2.5V to ±12V, settles 2V input steps to within one percent in just 23ns, and features 50ns overload recovery time. The maximum supply current is 7.7mA for ±5V supplies. The supply current can be reduced down to 1.3mA with an output-disable feature. It exhibits stability over temperature, with input offset voltage and input bias current drifts rated at 0.5µV/degree C and 10nA/degree C, respectively.
Housed in low-profile, eight-pin SOIC and micro-SOIC packages, and specified for operation over -40 to 85 degrees C, the device is priced at $1.20 in 10,000-piece quantities.
