Voltage References Replace Hard-To-Find Maxim Parts

The TSM6025A and TSM6025B voltage reference ICs from Touchstone Semiconductor are pin-compatible and specification-identical to hard-to-get MAX6025A/B Maxim parts. The TSM6025A/B consume 27 μA of supply current at no-load, and exhibit an initial output voltage accuracy of less than 0.2% and a low output voltage temperature coefficient of 15 ppm/°C. In addition, the TSM6025A/B’s output stage is stable for all capacitive loads to 2200 pF and is capable of sinking and sourcing load currents up to 500 μA. Prices start at $1.70 each/1,000.
