The MSK 0033(B) is a high speed, wide bandwidth voltage follower/buffer amplifier that is pin compatible with all other 0033 designs. The FET input is cascaded to force the input characteristics to remain constant over the full input voltage range. Significantly improved performance in sample and hold circuits is achieved since the DC bias current remains constant with input voltage. The FET input also makes the MSK 0033 very accurate since it produces extremely low input bias current, input offset voltage and input offset voltage drift specifications. Transistion times in the range of 2.5 nS make the MSK 0033 fast enough for most high speed voltage follower/buffer amplifier applications.
