This datasheet introduces the SMP04, a monolithic quad sample-and-hold with four internal precision buffer amplifiers and internal hold capacitors. It is manufactured in ADI’s advanced oxide isolated CMOS technology to obtain the high accuracy, low droop rate and fast acquisition. It is suitable for signal processing systems, multichannel data acquisition systems, automatic test equipment, medical and analytical instrumentation, event analysis and DAC deglitching.
The SMP04 quad sample‑and‑hold amplifier provides four independent channels, each with its own input, output, control, and on‑chip hold capacitor. It is fabricated in ADI’s oxide‑isolated CMOS technology for high accuracy, low droop (2 mV/s typical), and fast acquisition times, making it suitable for data‑acquisition, test equipment, and medical instrumentation.
The device operates from single or dual supplies (7 V to 15 V) and is available in 16‑lead ceramic DIP, plastic DIP, and SOIC packages. It includes TTL/CMOS compatible logic inputs, output buffers capable of sourcing 1.2 mA and sinking 0.5 mA, and a typical supply current of 4 mA. Detailed specifications, absolute maximum ratings, and layout recommendations are provided for optimal performance.
