TECHNICAL NOTES
The SHM-12 employs an open loop architecture to achieve its
superior high-speed characteristics. The first stage buffer
amplifier incorporates the sample-and-hold switch. This allows
for a fast acquisition time which is not limited by slew current
like the traditional Schottky diode bridge switch. The output
amplifier uses a closed loop voltage feedback design which
provides a low (0.3
, typical) output impedance. Gain and
linearity are not affected by heavy loads.
The design has been optimized to achieve the high accuracy
associated with fast transient responses over the military tem-
perature range. During the track-to-hold transient, the integral
nonlinearity is not affected and the pedestal remains constant
over the full ±1.5V input range.
An innovative circuit design ensures an extremely low droop rate.
An external hold capacitor can be added to the 15pF internal
hold capacitor to obtain a lower droop rate (the droop rate is pro-
portional to the inverse of the total hold capacitor value) without
increasing transient response times by more than a few ns. The
external hold capacitor should not exceed 100pF.
Footnotes:
Short circuit protection at ±50mA.
