*PQFP package type. This column lists the data format for the bus with ÒµPÓ indicating microprocessor capability Ñ i.e., for a 12-bit converter 8/12, µP indicates that the data can be formatted for an 8-bit bus or can be in parallel (12 bits) and is microprocessor
compatible. àExt. indicates external reference with the range of voltages listed where applicable. Ext. (M) indicates external reference with multiplying capability. Int. indicates reference is internal. A voltage value is given if the reference is pinned out.

Analog Switches and Multiplexers
Analog Devices offers a complete line of monolithic analog multiplexers and switches which are well suited for a wide
range of applications including data acquisition, process control, instrumentation, video systems and telephone systems.
Solid-state analog multiplexers and switches provide the ability to control and select a specified transmission path for an
analog signal. In selecting analog multiplexers and switches attention must be paid to several key specifications which
affect system performance, including ON Resistance (Ron) and Analog Input Leakage Current (Isoff).

Sample/Track-and-Hold Amplifiers
A sample/track-and-hold amplifier (SHA/THA) is a device that samples an analog input signal then holds the instantaneous value upon the command of a logic
control signal. This device is basically an analog memory where a capacitor serves as the storage element.
Popular applications utilizing the sample-and-hold function include data acquisition in which the SHA is used to capture the last instantaneous sampled analog input
voltage prior to a conversion and hold this sample with minimal degradation during the conversion process. SHAs/THAs are also popular in signal processing
applications using ADCs with a subranging or successive approximation architecture.
Significant improvement in dynamic performance can be made by placing fast SHAs with low aperture jitter ahead of flash ADCs. SHAs are also useful in
applications including D/A deglitchers, simultaneous sampling systems, peak detectors, pulse stretchers, delay lines and data distribution systems.
