1.1

The l denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. (Note 4)

Note 1. Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2. All voltage values are with respect to ground.

Note 3. When these pin voltages are taken below ground or above VDD

(AIN, REF) or OVDD (SCK, CS, SDO) they will be clamped by internal

diodes. This product can handle input currents up to 100mA below ground

or above VDD or OVDD without latch-up.

Note 4. VDD = 5V, OVDD = 2.5V, fSMPL = 5MHz, fSCK = 87.5MHz, AIN =

–1dBFS and internal reference unless otherwise noted.

Note 5. Integral nonlinearity is defined as the deviation of a code from a

straight line passing through the actual endpoints of the transfer curve.

The deviation is measured from the center of the quantization band.

Note 6. Linearity, offset and gain specifications apply for a single-ended

AIN input with respect to ground.

Note 7. Typical RMS noise at code transitions.

Note 8. Parameter tested and guaranteed at OVDD = 2.5V. All input signals

are specified with tr = tf = 1nS (10% to 90% of OVDD) and timed from a

voltage level of OVDD/2.

Note 9. All timing specifications given are with a 10pF capacitance load.

Load capacitances greater than this will require a digital buffer.

Note 10. The time required for the output to cross the VIH or VIL voltage.

Note 11. Guaranteed by design, not subject to test.

Note 12. Recommended operating conditions.
