TA = +25°C, Not addressed, SCL = SDA = RESET = VDD = 1.6V, Power-down supply current 0.07 0.8 µA PINTDAV = 1 (5) The TSC2011 can work with a supply voltage down to 1.2V if the internal clock is set to 1MHz (slow) and an ADC long sampling time is used. To set the internal clock to 1MHz CL[1:0] = "10" or "11" and LSM of Configuration register 0 is set to "1". Note that the I2C interface High speed Mode is limited to 1.7MHz. Check with the factory for further details, if needed. (6) For detailed information on test condition parameter and bit settings, see the Digital Interface section. (7) Touch sensor modeled by: 2k Ω for X-plane and Y-plane, and 1kΩ for Z (touch resistance), in the single-touch scenario. 4 Submit Documentation Feedback Copyright © 2011, Texas Instruments Incorporated Product Folder Link(s): TSC2011 |
