ADS7835E Burr-Brown Corporation, ADS7835E Datasheet - Page 2

• Manufacturer Part Number: ADS7835E
• Description: 12-Bit/ High-Speed/ Low Power Sampling ANALOG-TO-DIGITAL CONVERTER
• Manufacturer: Burr-Brown Corporation

SPECIFICATIONS
NOTES: (1) Ideal input span, does not include gain or offset error. (2) LSB means Least Significant Bit, with V
relative to an ideal positive full scale of 2.499V for positive full-scale error. Measured relative to an ideal negative full scale of –2.499V for negative full-scale error.
(4) Calculated on the first nine harmonics of the input frequency. (5) If the internal reference is required to source current to an external load, the reference voltage
will change due to the internal 10k
