Cost of sample-and-hold circuits is reduced by using high slew rate only during sample period. Programmable μA776 opamp permits switching from high rate requiring 50-nA input bias current to holding amplifier mode requiring only 750-pA input bias current. Output level is held constant within 1% for about 2 s, making circuit ideal for digital readouts.-M. K. Vander Kooi, Low Cost Sample-and-Hold Circuit, EDN/EEE Magazine, Nov.1,1971, p 46.
