Cocked and ready for the portable products market, the MAX1115 through MAX1119 family of a/d converters comes in an eight-pin SOT23 package. This family of eight-bit devices offers 3V or 5V single-supply operation, internal or external references, and one or two input channels.
Power consumption is just 175 µA, 135 µA for the MAX1118, and sampling rate is 100 ksamples/s. Power consumption lowers to 18 µA at 10 ksamples/s and under 5 µA at lower sample rates. Depending on the model, full scale analog input range is determined by an internal, 2.048V or 4.096V reference voltage or an external reference in the 1V to Vdd range.
The devices' serial interface connects directly to SPI, QSPI and MICROWIRE devices without external logic. All are available with an operating temperature range from –40°C to +85°C and prices start at $0.99 each/1,000.
