MAX1116 Datasheet | Maxim Integrated

Description The MAX1115/MAX1116 low-power, 8-bit, analog-todigital converters (ADCs) feature an internal track/hold (T/H), voltage reference, VDD monitor, clock, and serial interface. The MAX1115 is specified from +2.7V to +5.5V, and the MAX1116 is specified from +4.5V to +5.5V. Both parts consume only 175µA at 100ksps. The full-scale analog input range is determined by the internal reference of +2.048V (MAX1115) or +4.096V (MAX1116). The MAX1115/MAX1116 also feature Auto Shutdown™ power-down mode which reduces power consumption to <1µA when the device is not in use. The 3-wire serial interface directly connects to SPI™, QSPI™, and MICROWIRE™ devices without external logic. Conversions up to 100ksps are performed using an internal clock. The MAX1115/MAX1116 are available in an 8-pin SOT23 package with a footprint that is just 30% of an 8-pin SO. o Single Supply +2.7V to +3.6V (MAX1115) +4.5V to +5.5V (MAX1116) o Input Voltage Range: 0 to VREF o Internal Track/Hold; 100k Hz Sampling Rate o Internal Reference +2.048V (MAX1115) +4.096V (MAX1116) o SPI/QSPI/MICROWIRE-patible Serial Interface o Small 8-Pin SOT23 Package o Automatic Power-Down o Low Power 175µA at 100ksps 18µA at +3V and 10ksps 1µA in Power-Down Mode Features MAX1115/MAX1116 ________________________Applications Low-Power, Hand-Held Portable Devices System Diagnostics Battery-Powered Test Equipment Receive-Signal-Strength Indicators 4m A to 20m A Powered Remote Data-Acquisition Systems PART MAX1115EKA MAX1116EKA Ordering Information TEMP RANGE -40°C to +85°C -40°C to +85°C PINPACKAGE 8 SOT23 8 SOT23 TOP MARK AADU AADV Pin Configuration TOP VIEW VDD 1 8 7 SCLK DOUT CONVST I.C.
