The SMP18 is a high-precision, eight-channel sample-and-hold that features eight internal buffer amplifiers, an input multiplexer, and internal hold capacitors. It is manufactured in an advanced oxide isolated CMOS technology to achieve high accuracy, low droop rate, and fast acquisition time. The SMP18 has a typical linearity error of only 0.01% and can accurately acquire a 10-bit input signal.
The SMP18 is a monolithic octal sample‑and‑hold device featuring eight internal buffer amplifiers, an input multiplexer and internal hold capacitors. It offers high‑speed operation (typical acquisition time 3.5 µs), low droop rate (2 mV/s typical), and TTL/CMOS compatible logic inputs. The part is supplied in 16‑pin plastic DIP, narrow‑body SO‑16, and thin‑profile TSSOP‑16 packages.
Designed for systems that require calibrated voltage sets or multiplexed analog outputs, the SMP18 is used in memory programmers, mass‑flow control, data‑acquisition, robotics, medical instrumentation and stage‑lighting control. It supports single‑ or dual‑supply operation over a 7 V to 15 V range and includes break‑before‑make channel addressing compatible with CD4051 pinout.
The SMP18 can operate with single or dual supplies ranging from 7 V to 15 V.
The output buffers can source more than 20 mA over the full voltage range.
It is offered in a 16‑pin plastic DIP, a narrow‑body SO‑16 surface‑mount package, and a thin TSSOP‑16 package.
