The MAX1084/MAX1085 10-bit analog-to-digital converters (ADCs) combine a high-bandwidth track/hold, a serial interface with high conversion speed, an internal +2.5V reference, and low power consumption. The MAX1084 operates from a single +4.5V to +5.5V supply; the MAX1085 operates from a single +2.7V to +3.6V supply.The 3-wire serial interface connects directly to SPI™/QSPI™/MICROWIRE™ devices without external logic. The devices use an external serial-interface clock to perform successive-approximation analog-to-digital conversions.Low power combined with ease of use and small package size make these converters ideal for remote-sensor and data-acquisition applications, or for other circuits with demanding power consumption and space requirements. The MAX1084/MAX1085 are available in 8-pin SO packages.These devices are pin-compatible, higher-speed versions of the MAX1242/MAX1243; for more information, refer to the respective data sheets.ApplicationsBattery-Powered ApplicationsData AcquisitionMedical InstrumentsPen DigitizersPortable Data LoggingProcess Control

The MAX1086–MAX1089 are low-cost, micropower, serial output 10-bit analog-to-digital converters (ADCs) available in a tiny 8-pin SOT23. The MAX1086/MAX1088 operate with a single +5V supply. The MAX1087/MAX1089 operate with a single +3V supply. The devices feature a successive-approximation ADC, automatic shutdown, fast wake-up (1.4µs), and a high-speed 3-wire interface. Power consumption is only 0.5mW (VDD= +2.7V) at the maximum sampling rate of 150ksps. AutoShutdown™ (0.1µA) between conversions results in reduced power consumption at slower throughput rates.The MAX1086/MAX1087 provide 2-channel, single-ended operation and accept input signals from 0 to VREF. The MAX1088/MAX1089 accept true-differential inputs ranging from 0 to VREF. Data is accessed using an external clock through the 3-wire SPI™, QSPI™, and MICROWIRE™-compatible serial interface. Excellent dynamic performance, low-power, ease of use, and small package size, make these converters ideal for portable battery-powered data acquisition applications, and for other applications that demand low power consumption and minimal space.ApplicationsAutomated Test Equipment (ATE)Automotive Passenger CompartmentAutomotive SensorsIndustrial Sensor Transmitters/TransducersIndustrial Sensor Transmitters/TransducersMotor and Motion ControlPortable Patient Monitoring/DeliveryPortable Test MetersProgrammable Logic ControllersSensor-ForceSensors-PressureTest and Measurement EquipmentX-Ray and Ultrasound Diagnostics

The MAX1090/MAX1092 low-power, 10-bit analog-to-digital converters (ADCs) feature a successive-approximation ADC, automatic power-down, fast wake-up (2µs), an on-chip clock, +2.5V internal reference, and a high-speed, byte-wide parallel interface. The devices operate with a single +5V analog supply and feature a VLOGICpin that allows them to interface directly with a +2.7V to +5.5V digital supply.Power consumption is only 10mW (VDD= VLOGIC) at a 400ksps max sampling rate. Two software-selectable power-down modes enable the MAX1090/MAX1092 to be shut down between conversions; accessing the parallel interface returns them to normal operation. Powering down between conversions can cut supply current to under 10µA at reduced sampling rates.Both devices offer software-configurable analog inputs for unipolar/bipolar and single-ended/pseudo-differential operation. In single-ended mode, the MAX1090 has eight input channels and the MAX1092 has four input channels (four and two input channels, respectively, when in pseudo-differential mode).Excellent dynamic performance and low power, combined with ease of use and small package size, make these converters ideal for battery-powered and data-acquisition applications or for other circuits with demanding power consumption and space requirements.The MAX1090/MAX1092 tri-states active-low INT when active-low CS goes high. Refer to the MAX1060/MAX1064 if tri-stating active-low INT is not desired.The MAX1090 is available in a 28-pin QSOP package, while the MAX1092 comes in a 24-pin QSOP. For pin-compatible +3V, 10-bit versions, refer to the MAX1091/MAX1093 data sheet.ApplicationsData Acquisition SystemsData LoggingEnergy ManagementIndustrial Control SystemsPatient MonitoringTouch Screens
