AMS236AS 数据手册
Advanced Monolithic Systems FEATURES • Low Temperature Coefficient • Wide Operating Current Range • Guaranteed Temperature Stability • Max. 0.6Ω Dynamic Impedance (A grade) • ±1% Initial Tolerance Available AMS236/AMS336 VOLTAGE REFERENCE DIODE RoHS compliant APPLICATIONS • Power Supplies • Instrumentation • 8 Bit A/D, D/A Reference • Current Loop Measurement and Control Systems • Reference for 5V Systems GENERAL DESCRIPTION The AMS236/AMS336 are precision band-gap voltage reference diodes. These voltage reference features a very low dynamic impedance and good temperature coefficient, operating over a wide current range of 400µA to 10mA. On-chip trimming is used to provide tight tolerance and minimize temperature drift. A third terminal allows the reference voltage to be trimmed ±5%. The AMS236/AMS336 are used as a precision 2.5V low voltage reference for digital voltmeters, power supplies or op amp circuitry, and the 2.5V make it easy to obtain a stable reference from 5V logic supplies. The AMS236 is rated for operation over -25°C to +85°C while the AMS336 is rated over a 0°C to 70°C temperature range. The AMS236/AMS336 are available in TO-92 and SO-8 packages.

Operating Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Note 2: For elevated temperature operation, Tj max is: AMS236 +125°C AMS336 +100°C Thermal Resistance ϕ JA (junction to ambient) TO-92 170°C/W (0.125” leads) SO-8 165°C/W Note 3: Parameters identified with boldface type apply at temperature extremes. All other numbers apply at TA = TJ = 25°C. Note 4: Temperature stability for the AMS236/336 family is guaranteed by design. Design limits are guaranteed (but not 100% production tested) over the specified temperature and supply voltage ranges. These limits are not used to calculate outgoing quality levels. The average temperature coefficient is defined as the maximum deviation of reference voltage at all measured temperatures between the operating TMAX and TMIN, divided by TMAX - TMIN.
