The CSC2046 is 100% pin-compatible with the existing ADS7846, and will drop into the same socket. This allows for easy upgrade of current applications to the new version. The CSC2046 also has an on-chip 2.5V reference that can be used for the auxiliary input, battery monitor, and temperature measurement modes. The reference can also be powered down when not used to conserve power. The internal reference operates down to 2.7V supply voltage, while monitoring the battery voltage from 0V to 6V. The low-power consumption of < 0.75mW typ at 2.7V (reference off), high-speed (up to 125kHz sample rate), and on-chip drivers make the CSC2046 an ideal choice for battery-operated systems such as personal digital assistants (PDAs) with resistive touch screens, pagers, cellular phones, and other portable equipment. The CSC2046 is available in TSSOP-16, QFN-16, and VFBGA-48 packages and is specified over the -40C to +85C temperature range.

Exposure to absolute maximum conditions for extended periods may degrade device reliability. SHENZ HEN HAIWEI SEMICONDUCTOR CORP 2 HWCAT ELECTROSTATIC DISCHARGE SENSITIVITY CSC2046 This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. www..com PACKAGE/ORDERING INFORMATION(1) NOMINAL MAXIMUM SPECIFIED INTEGRAL PRODUCT PULLUP LINEARITY RESISTOR ERROR (LSB) VALUES LEAD DESIGNATOR RANGE PACKAGEPACKAGE TEMPERATURE MARKING PACKAGE ORDERING NUMBER MEDIA, QUANTITY TRANSPORT CSC2046 CSC2046-90 CSC2046 " CSC2046 " 50k 90k 50k " 50k " 2 2 2 " 2 " VFBGA-48 VFBGA-48 TSSOP-16 " QFN-16 " GQC GQC PW " RGV " -40C to +85C -40C to +85C -40C to +85C " -40C to +85C " AZ2046 AZ2046A CSC2046I " CSC2046 " CSC2046IGQCR CSC2046IGQCR-90 CSC2046IPW CSC2046IPWR CSC2046IRGVT CSC2046IRGVR Tape and Reel, 2500 Tape and Reel, 2500 Rails, 100 Tape and Reel, 2500 Tape and Reel, 250 Tape and Reel, 2500 NOTE: (1) For the most current specifications and package information, see the Package Option Addendum located at the end of this data sheet. |
