HA9P5320-5Z (RENESAS)

The HA9P5320-5Z is a 1ms precision Sample and Hold Amplifier designed for use in precision, high speed data acquisition systems. The circuit consists of an input transconductance amplifier capable of providing large amounts of charging current, a low leakage analog switch and an output integrating amplifier. The analog switch sees virtual ground as its load, therefore, charge injection on the hold capacitor is constant over the entire input/output voltage range. The pedestal voltage resulting from this charge injection can be adjusted to zero by use of the offset adjust inputs. The device includes a hold capacitor. However, if improved droop rate is required at the expense of acquisition time, additional hold capacitance may be added externally. This monolithic device is manufactured using the Intersil Dielectric Isolation Process, minimizing stray capacitance and eliminating SCRs.
