Description

The DS1843 is a sample-and-hold circuit RSSI Burst-Mode Sample-and-Hold Circuit in a 2mm x 2mm µDFN Package and is useful for capturing fast signals where board space is constrained. It includes a differential, high-speed switched capacitor input sample stage, offset nulling circuitry, and an output buffer. The DS1843 is optimized for use in optical line transmission (OLT) systems for burst-mode RSSI measurement in conjunction with an external sense resistor.

Key Features

• Fast Sample Time < 300ns
• Hold Time > 100µs
• Low Input Offset
