AD1403中文资料Low Cost, Precision 2.5 V IC References数据手册ADI规格书

描述 Description

The AD1403 and AD1403A are improved three-terminal, low cost, temperature compensated, bandgap voltage referenced that provide a fixed 2.5V output voltage for inputs between 4.5V and 40V.A unique combination of advanced circuit design and laser-wafer-trimmed thin-film resistors provides the AD1403/AD1403A with an initial tolerance of ±10mV and a temperature stability of better than 25ppm/°C.In addition, the low quiescent current drain of 1.5mA (max) offers a clear advantage over classical Zener techniques.

The AD1403 or AD1403A is recommended as a stable reference for all 8-, 10-, and 12-bit D-to-A converters that require an external reference.In addition, the wide input range of the AD1403/AD1403A allows operation with 5 volt logic supplies, making these devices ideal for digital panel meter applications and when only a single logic supply is available.

The AD1403 and AD1403A are specified for operation over the 0 to +70°C temperature range.The AD580 series of 2.5 volt precision IC references is recommended for applications where operation over the -55°C to +125°C range is required.

• The AD1403A offers improved initial tolerance over the industry-standard 1403A: ±10 mV versus ±25 mV at a lowercost.

• The three-terminal voltage in/voltage out operation of theAD1403/AD1403A provides a regulated output voltage withoutany external components.

• The AD1403/AD1403A provides a stable 2.5 V output voltagefor input voltages between 4.5 V and 40 V making thesedevices ideal for systems that contain a single logic supply.

• Thin film resistor technology and tightly controlled bipolarprocessing provide the AD1403A with temperature stabilitiesof 25 ppm/°C.

• The low 1.5 mA maximum quiescent current drain of theAD1403 and AD1403A makes them ideal for CMOS andother low power applications.
