Wideband noise is 3nV/VHz, at 10Hz., with a low 1/f noise corner frequency of'2.7Hz. The OP-27's exceptionally low noise process allows for accurate high-gain amplification of low level signals. A gain-bandwidth product of 8MHz and a 2.8V/usec slew rate provides excellent dynamic accuracy in high-speed data-acquisition. Calogics advanced low noise process and design techniques make the OP-27 an | OP-27 excellent choice for reliable, precision amplifier applications. The low input bias current of 10nA and offset current of 7nA are achieved by using a bias-current-cancellation circuit. Over the military temperature range this typically holds tg and Iog to +20nA and +15nA respectively. PSRR and CMRR exceed 120db. PRODUCT HIGHLIGHTS: 1. Precision amplification of very low level, low frequency voltage inputs is enhanced by ultra-low input voltage noise. 2. The OP-27 maintains high DC accuracy due to ultra-low | offset voltage, offset voltage drift and input bias current. 3. Internal frequency compensation, factory adjusted offset voltage (zener-zapped) and full device protection eliminate the need for additional components. 4. Long-term stability and accuracy is assured with low offset voltage drift over time. ' 5. Input errors are greatly reduced by superior common mode and power supply rejection. 6. Radiation hardenable to beyond 5 M Rads.
