2.5-V INTEGRATED REFERENCE CIRCUIT

The LT1009 reference circuit is a precision-trimmed 2.5-V Shunt Regulator featuring low dynamic impedance and a wide operating current range. The reference tolerance is achieved by on-chip trimming, which minimizes the initial voltage tolerance and the temperature coefficient, α VZ . Although the LT1009 needs no adjustments, a third terminal (ADJ) allows the reference voltage to be adjusted ± 5% to eliminate system errors. In many applications, the LT1009 CAN be used as a terminal-for-terminal replacement for the LM136-2.5, which eliminates the external trim network. The LT1009 uses include 5-V system references, 8-bit Analog-to-digital converter (ADC) and digital-to-analog converter (DAC) references, and power-supply monitors. The device also CAN be used in applications such as digital voltmeters and current-loop measurement and control systems. The LT1009 is characterized for operation from – 55 ° C to 125 ° C.
