Packages: TO-92 and SOT-23-3 Industrial Temperature Range: -40°C to +85°C Applications Battery-powered Systems Handheld Instruments Instrumentation and Process Control Test Equipment Data Acquisition Systems Communications Equipment Medical Equipment Precision Power supplies 8-bit, 10-bit, 12-bit A/D Converters (ADCs) D/A Converters (DACs) Typical Application Circuit VREF VDD CIN 0.1 µF (optional) MCP1525 MCP1541 VIN VSS VOUT CL 1 µF to 10 µF Basic Configuration Description The Microchip Technology Inc. MCP1525/41 devices are 2.5V and 4.096V precision voltage references that use a combination of an advanced CMOS circuit design and EPROM trimming to provide an initial tolerance of ±1% (max.) and temperature stability of ±50 ppm/°C (max.). In addition to a low quiescent current of 100 µA (max.) at 25°C, these devices offer a clear advantage over the traditional Zener techniques in terms of stability across time and temperature. The output voltage is 2.5V for the MCP1525 and 4.096V for the MCP1541. These devices are offered in SOT-23-3 and TO-92 packages, and are specified over the industrial temperature range of -40°C to +85°C. MCP1525 Output Voltage (V) MCP1541 Output Voltage (V) ...
