*Notice: Stresses above those listed under “Maximum

ratings” may cause permanent damage to the device. This is

a stress rating only and functional operation of the device at

those or any other conditions above those indicated in the

operational listings of this specification is not implied.

Exposure to maximum rating conditions for extended periods

may affect device reliability.

ELECTRICAL SPECIFICATIONS

Electrical Characteristics: Unless otherwise noted, all parameters apply at VDD = 5V, VSS = 0V, and VREF = 5V. Full differential

input configuration (Figure 1-5) with fixed common mode voltage of 2.5V. All parameters apply over temperature with

TAMB = -40°C to +85°C (Note 7). Conversion speed (FSAMPLE) is 100 ksps with FCLK = 17*FSAMPLE

Note

1: This specification is established by characterization and not 100% tested.

2: See characterization graphs that relate converter performance to VREF level.

3: VIN = 0.1V to 4.9V @ 1 kHz.

4: VDD = 5V DC ±500 mVP-P @ 1 kHz, see test circuit Figure 1-4.

5: Maximum clock frequency specification must be met.

6: VREF = 400 mV, VIN = 0.1V to 4.9V @ 1 kHz

7: MSOP devices are only specified at 25°C and +85°C.

8: For slow sample rates, see Section 5.2.1 “Maintaining Minimum Clock Speed” for limitations on clock frequency.

9: 4.5V - 5.5V is the supply voltage range for specified performance
