Op amp combines low voltage noise and THD
The AD797 monolithic op amp has a voltage noise of 0.9 nV/
1 kHz and THD of -120 dB at 20 kHz. In addition, the device's voltage
noise remains flat over the full 8-MHz bandwidth at a gain of 10. The
AD797 has a guaranteed 1.2-microsecond settling time to 16 bits, a 110-MHz
gain-bandwidth product, and a 20-V/μs slew rate. Other specifications
include maximum voltage offset and drift of 60 microvolts and 0.6
microvolts/ degreesC, respectively, and a typical input offset current of
200 nA. The AD797 operates from +/-5 to +/-15-V supplies and comes in
8-pin plastic DIPs, CerDIPs, and SO packages. (From $3.36 ea/1,000–stock.
