MAXIM MAX6610AUT+T

The MAX6610/MAX6611 are precise, low-power analog temperature sensors combined with a precision voltage reference. They are ideal for applications involving analog-to-digital converters (ADCs), where the MAX6610/MAX6611 provide the reference voltage for the ADC and develop a temperature output voltage that is scaled to provide convenient ADC output codes. An 8-bit ADC’s LSB is equal to 1℃, while a 10-bit ADC’s LSB corresponds to 0.25℃. The MAX6610/MAX6611 are available in two versions. The MAX6611 operates from a 4.5V to 5.5V power supply and has a 4.096V reference output. The MAX6610 operates from 3.0V to 5.5V and has a 2.560V reference output. Power-supply current is less than 150μA (typ). Both the MAX6610/MAX6611 are available in a 6-pin SOT23 package and operate from -40℃ to +125℃. The MAX6610/MAX6611 combine a temperature sensor with a low-power voltage reference. The reference voltage and temperature sensor gain give convenient LSB weights when used with an ADC. For example, when an 8-bit ADC is used with the MAX6610/MAX6611, an LSB is equivalent to 1℃ and a 10-bit ADC LSB is equivalent to 0.25℃. The reference output features a proprietary temperature-coefficient, curvature-correction circuit and lasertrimmed thin-film resistors that result in a low temperature coefficient (5099m/℃ max) and initial accuracy of ±0.5% max. The maximum supply current is 250μA during normal operation and 1μA max during shutdown. The supply voltage range is 3.0V to 5.5V for the MAX6610 and 4.5V to 5.5V for the MAX6611. The MAX6610/MAX6611 REF output provides a voltage reference for ADCs or other system subcircuits. REF is capable of driving loads of up to 1mA. An output capacitor can be as large as 1µF. The voltage reference provides scaled ADC conversions with bit weights that are in convenient units. For the MAX6610 (2.56V REF output), an 8-bit ADC yields 10mV/bit or 2.5mV/bit for a 10-bit ADC. The MAX6611 (4.096V REF output) yields 16mV/bit for an 8-bit ADC or 4mV/bit for a 10-bit ADC. The MAX6610/MAX6611 TEMP output provides an analog output voltage that is a linear function of its die temperature as defined by: V_TEMP = 1.2V+(T℃ × 16mV/℃)
