SHM-14 14-Bit Linear Sample-Hold Amplifier GENERAL DESCRIPTION The SHM-14 is an extremely high-speed and accurate sample-and-hold amplifier designed for fast data acquisition applications. The SHM-14 is accurate (±0.5 LSB to 14-bit over the full military temperature range) and is very fast (25ns and 35ns acquisition times to accuracies of 12 and 14 bits respectively). With this high performance and a full power bandwidth of 60MHz, the SHM-14 is an ideal device for high resolution data acquisition systems. Careful design optimizes the device for accuracy and speed over the full military temperature range. Operating from ±5V supplies, the SHM-14 consumes only 275mW of power and has high drive capability. The SHM-14 is available with solder dipped leads in both military and commercial temperature ranges. RoHS compliant versions are also available if required. The device is packaged in a 16-pin hermetically sealed ceramic LCC package.

Mount all components as close to the required pins as possible. It is strongly recommended that the SHM-14 not be socket-mounted. Obtaining fully specified performance from the SHM-14 requires careful attention to pc-board layout and power supply decoupling. For optimal performance, tie all grounds directly to a large analog ground plane beneath and around the package. Bypass all power supplies to ground with 10μF tantalum capacitors in parallel with 0.1μF ceramic capacitors. Locate the bypass capacitors as close to the unit as possible.
