What is the Surface Mount ?

having leads that are designed to be soldered on the side of a circuit board that the body of the component is mounted on.

What is the Operating Temperature ?

The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

What is the Packaging ?

Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.

What is the Part Status ?

Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.

What is the Terminal Form ?

Occurring at or forming the end of a series, succession, or the like; closing; concluding.

What is the Terminal Pitch ?

The center distance from one pole to the next.

What is the Max Supply Voltage ?

In general, the absolute maximum common-mode voltage is VEE-0.3V and VCC+0.3V, but for products without a protection element at the VCC side, voltages up to the absolute maximum rated supply voltage (i.e. VEE+36V) can be supplied, regardless of supply voltage.

What is the Min Supply Voltage ?

The minimum supply voltage (V min ) is explored for sequential logic circuits by statistically simulating the impact of within-die process variations and gate-dielectric soft breakdown on data retention and hold time.

What is the Nominal Supply Current ?

Nominal current is the same as the rated current. It is the current drawn by the motor while delivering rated mechanical output at its shaft.

What is the Quiescent Current ?

The quiescent current is defined as the current level in the amplifier when it is producing an output of zero.

What is the Synchronous Rectifier ?

Synchronous rectification is a technique for improving the efficiency of rectification by replacing diodes with actively controlled switches, usually power MOSFETs or power bipolar junction transistors (BJT).

What is the RoHS Status ?

RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.

DS2165Q/T&R DESCRIPTION

The DS2165Q ADPCM processor chip is a dedicated digital-signal-processing (DSP) chip that has beenoptimized to perform adaptive-differential pulse-code modulation (ADPCM) speech compression at threedifferent rates. The chip can be programmed to compress (expand) 64kbps voice data down to (up from)either 32kbps, 24kbps, or 16kbps. The compression to 32kbps follows the algorithm specified by CCITTRecommendation G.721 (July 1986) and ANSI document T1.301 (April 1987). The compression to24kbps follows ANSI document T1.303. The compression to 16kbps follows a proprietary algorithmdeveloped by Dallas Semiconductor. The DS2165Q can switch compression algorithms on-the-fly. Thisallows the user to make maximum use of the available bandwidth on a dynamic basis.Note: Some revisions of this device may incorporate deviations from published specifications known as errata. Multiplerevisions of any device may be simultaneously available through various sales channels. For information about device errata,click here: http://www.maxim-ic.com/errata.1 of 17070802
