Maxim : Sample-and-hold IC captures 300 ns signals

The DS1843, a fast sample-and-hold circuit in a 2 x 2 mm microDFN package, can capture signals of less than 300 ns on its differential inputs and hold them at the output for up to 100 us. A low input offset voltage (~5 mV) ensures accurate measurements. The circuit includes a differential, high-speed, switched-capacitor input sample stage, offset-nulling circuitry, and an output buffer. Through this integration, the IC saves considerable board space as compared to discrete approaches.

The DS1843 is optimized for burst-by-burst RSSI measurement in GPON OLT systems in conjunction with an external sense resistor. It is fully specified over the -40 to +85 °C extended temperature range.

Pricing begins at $0.70 (1000-up, FOB USA).
