MXB7843EUE+ General Description

The MXB7843 is an industry-standard 4-wire touch-screen controller. It contains a 12-bit sampling analog-to-digital converter (ADC) with a synchronous serialinterface and low on-resistance switches for drivingresistive touch screens. The MXB7843 uses an externalreference. The MXB7843 can make absolute or ratio-metric measurements. The MXB7843 has two auxiliaryADC inputs. All analog inputs are fully ESD protected,eliminating the need for external TransZorb™ devices.The MXB7843 is guaranteed to operate with a single2.375V to 5.25V supply voltage. In shutdown mode, thetypical power consumption is reduced to under 0.5µW,while the typical power consumption at 125kspsthroughput and a 2.7V supply is 650µW.Low-power operation makes the MXB7843 ideal for bat-tery-operated systems, such as personal digital assis-tants with resistive touch screens and other portableequipment. The MXB7843 is available in 16-pin QSOPand TSSOP packages, and is guaranteed over the-40°C to +85°C temperature range.
