Sample and Hold Amplifier
Sample and Hold
General Description
The LH0053/LH0053C is a high speed sample and hold
circuit capable of acquiring a 20V step signal in under
5.0I-ls.
The device is ideally suited for a variety of high speed
data acquisition applications including analog buffer
memories for A to D conversion and synchronous de-
modulation.
Features
• Sample acquisition time 10",s max. for 20V signal
• FET switch for preset or reset function
• Sample accuracy null
• Offset adjust to OV
• DTLlTTL compatible FET gate
• Single storage capacitor

=Note 1: Unless otherwise noted, these specifications apply for Vs ±15V, pin 9 grounded, a 1000 pF capacitor between pin 5 and pin 11,
pin 3 shorted to pin 11, over the temperture range -55°C to +125°C for the LH0053 and -25°C to +85°C for the LH0053C. All typical
=values are for TA 25°C.
Note 2: Sample accuracy may be nulled by inserting a potentiometer in the feedback loop. This compensates for source impedance
and feedback resistor tolerances.
