DCPs feature lowest supply voltages and power consumption
1 min read
Intersil has developed a series of single, dual and quad digitally controlled potentiometers (dcps) which it claims feature the industry's lowest supply voltages, power consumption and noise.
According to the company, the ISL233x5 and ISL234x5 provide 'the most flexible and reliable solution wherever a voltage or resistor setting is needed'.
Supply current is as low as 2.8uA at 5V, which Intersil describes as '40% to 50% lower than most competitive devices'. Analogue supply voltage can range from 1.7 to 5.5V and the digital supply voltage may be even lower at 1.2 to 5.5V, eliminating the need for a level shifter if the mcu has low voltage digital interface outputs. Wiper position can be controlled through either the I2C or SPI interface.
The eds tolerance is 6.5kV HBM and the dcps are offered in both leaded and microTQFN packages, which can be ordered with 10, 50 or 100kOhm total resistances. The devices have been designed for use as three terminal potentiometers or as two terminal variable resistors in portable medical instrumentation, network cards, smartphones, regulator margining and applications requiring calibration or digital control.
