The LND-PKD310
Peak Sample & Hold with Offset + Amplifier
What is the LND-PKD310?
The LND-PKD310 is a versatile peak sample and hold IC with digitally
programmable gain (1-16x), two DC level shifters, and very accurate peak
detect circuit. All functions of this IC are controlled by microcontroller; this
product is considered a microcontroller peripheral device.
How does it work?
· Connect Vcc and Gnd, connect the clock signal.
· Reset the device by holding M and D low for at least 64 clock cycles.
This will clear all registers.
· Load level shift registers A and B, and set the programmable gain on
the opamp.
· Connect input signal to In.
· Initiate sample and hold with microcontroller, the resulting peak value
will be on Out.
· Ensure that the sample time is long enough to ensure that a full
waveform passes through the device.
How Do I get samples?
The LND-PKD310 is available in 28 pin ceramic package. For volume orders,
Linear Dimensions can package this device is industry standard packaging
including a SOIC-28. Please contact your Linear Dimensions representative
for more information or www.lineardimensions.com.
