Overview
The LTC6994CDCB-1#TRPBF is a programmable delay block manufactured by Analog Devices Inc. and is part of the TimerBlox family of versatile silicon timing devices. This component offers a wide range of delay times, from 1µs to 33.6 seconds, making it highly versatile for various timing applications. The delay time is programmed using a single resistor (RSET) that sets the internal master oscillator frequency, and the device can also dynamically adjust the delay time via a separate control voltage.
