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.

ATR2731-ILSY 1. Description

The ATR2731 is a monolithically integrated Digital Audio Broadcasting one-chip front-end circuitmanufactured using Atmel’s advanced UHF5S technology. Its functionality covers a gain-con-trolled RF amplifier with two selectable RF inputs, a gain-controlled RF mixer, a VCO whichprovides the LO signal for the RF mixers, either directly or after passing a frequency divider, aSAW filter driver, an AGC block for the RF section, a gain-controlled IF amplifier, an IF mixerwhich can also be bypassed, an AGC block for the IF section, and a fractional-N frequency syn-thesizer. The frequency synthesizer controls the VCO to synthesize frequencies in the range of70 MHz to 500 MHz in a 16-kHz raster; within certain limits, the reference divider factor is fullyprogrammable.The lock status of the phase detector is indicated at a special output pin; three switching outputscan be addressed. A reference signal, generated by an on-chip reference oscillator, is availableat an output pin. This reference signal is also used to generate the LO signal for the IF mixer,either by doubling the frequency or by using the reference frequency itself. Three D/A convertersat a resolution of 8 bits provide a digitally controllable output voltage. The thresholds inside theAGC blocks can be digitally controlled by means of on-chip 4-bit D/A converters. All functions ofthis IC are controlled via a simple two-wire bus.2
