Basic Cellular Phone
A basic entry-level cellular phone offers voice and text-messaging capability. Key features are low cost, minimal component count, and ease of design, often aided by reference designs. Analog Devices offers complete chipsets for entry-level GSM/GPRS phones that meet these criteria, and offer flexibility for easy feature addition to cover a range of end-products.

Application Notes
AN-625: Modifying the Range of the ADXRS150 and ADXRS300 Rate Gyros (pdf, 71,524 bytes)
AN-601: Minimizing Power Consumption of iMEMS® Accelerometers (pdf, 559,730 bytes)
AN-588: AD7416/AD7417/AD7418 Power-On Reset Circuit (pdf, 30,326 bytes)
If a large number of decoupling capacitors are used on the VDD line, re-applying power before VDD has discharged to 0 V can cause the AD7416/AD7417/AD7418 to reset into an unknown. state.
AN-577: Layout and Grounding Recommendations for Touch Screen Digitizers (pdf, 53,905 bytes)
AN-573: OP07 Is Still Evolving (pdf, 159,635 bytes)
AN-561: AD7416 Connects to the PIC16F84 via Emulated I²C™ Interface (pdf, 75,851 bytes)
AN-417: Fast Rail-to-Rail Operational Amplifiers Ease Design Constraints in Low Voltage High Speed Systems (pdf, 234,127 bytes)
Movement towards lower power supply voltages is driven by the demand that systems consume less and less power coupled with the desire to reduce the number of power supply voltages in the system. The following applications are discussed: Single-Ended and Differential Input ADC Input Circuits, Video Line Driver, Active Filter, HDSL Transceiver, and Transformer Drive Circuits.
