The Maxim ICL7136 is a monolithic analog to digital converter with very high input impedance. On-board active components include segment drivers, segment decoders, voltage reference and a clock circuit. The ICL7136 directly drives a non-multiplexed liquid crystal (LCD) display, requiring no external display drive circuitry. Significantly reduced power consumption makes the ICL7136 a superior device, especially for portable systems.Versatility and accuracy are inherent features of this converter. The dual-slope conversion technique automatically rejects interference signals common in industrial environments. The true differential input and reference are particularly useful when making ratiometric measurements (ohms or bridge transducers), and the zero-integrator phase in Maxim's ICL7136 eliminates overrange hangover and hysteresis effects. Finally, this device offers high accuracy by lowering rollover error to less than one count and zero reading drift to less than 1μV/°C.ApplicationsConductanceCurrentMaterial ThicknessPressureResistanceSpeedTemperatureVoltage

The MAX1044 and ICL7660 are monolithic, CMOS switched-capacitor voltage converters that invert, double, divide, or multiply a positive input voltage. They are pin compatible with the industry-standard ICL7660 and LTC1044. Operation is guaranteed from 1.5V to 10V with no external diode over the full temperature range. They deliver 10mA with a 0.5V output drop. The MAX1044 has a BOOST pin that raises the oscillator frequency above the audio band and reduces external capacitor size requirements.The MAX1044/ICL7660 combine low quiescent current and high efficiency. Oscillator control circuitry and four power MOSFET switches are included on-chip. Applications include generating a -5V supply from a +5V logic supply to power analog circuitry. For applications requiring more power, the MAX660 delivers up to 100mA with a voltage drop of less than 0.65V.Applications-5V Supply from +5V Logic SupplyData AcquisitionEIA/TIA-232E and EIA/TIA-562 Power SuppliesHandheld Instruments (PDAs, Palmtops)Op-Amp Power SuppliesPanel MetersPersonal Communications EquipmentPortable Telephones

The ICL7109 is a monolithic 12 bit A/D converter designed for easy interface with microprocessors and UARTs. The 12 bit binary plus polarity and over-range outputs can be directly interfaced to a microprocessor bus. In this mode the ICL7109 is controlled by the microprocessor through the chip select and tow byte enable inputs. For remote data logging applications the ICL7109 outputs are easily converted to a UART handshake mode, working with industry standard UARTs to provide serial data transmission.This device offers high accuracy by lowering rollover error to less than 1 count and zero reading drift to less than 1μV/ °C. In many data acquisition systems the ICL7109 is an attractive, low cost, one-per-channel alternative to analog multiplexing due to its low power consumption and input bias current.Maxim has added a zero-integrator phase to the ICL7109, eliminating overrange hangover, 'crosstalk' and hysteresis effects. Maxim has also increased the current sourcing capabilities of the ICL7109, enabling it to rapidly drive the large capacitances often found on microprocessor busses.ApplicationsCurrentFlowPowerPressureResistanceSpeedTemperatureVoltageWeight
