... Hz and a low input offset voltage of 0.3 mV maximum (AD840K). The 400 V/ s slew rate of the AD840, along with its 400 MHz gain bandwidth, ensures excellent performance in video and pulse amplifier applications. This amplifier is ideally suited for use in high frequency signal conditioning circuits and wide REV ...

... REV. C Figure 24 shows the “long-term” stability of the settling charac- teristics of the AD840 output after step. There is no evi- dence of settling tails after the initial transient recovery time. The use of a junction isolated process, together with careful lay- ...

... AD840 HIGH SPEED DAC BUFFER CIRCUIT The AD840’s 100 ns settling time to 0.01% for step makes it well suited as an output buffer for high speed D/A con- verters. Figure 25 shows the connections for producing +10.24 V output swing from the AD568 35 ns DAC. With the AD568 in unbuffered voltage output mode, the AD840 is placed in noninverting configuration ...
