ELECTRICAL SPECIFICATIONS (CONTINUED)

Electrical Characteristics: Unless otherwise noted, all parameters apply at V_DD= 5V, V_SS= 0V, and V_REF= 5V. Full differential

input configuration (Figure 3-4) with fixed common mode voltage of 2.5V. All parameters apply over temperature with

T_AMB= -40°C to +85°C (Note 7). Conversion speed (F_SAMPLE) is 100 ksps with F_CLK= 21*F_SAMPLE

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

2: See characterization graphs that relate converter performance to V_REFlevel.

V_IN= 0.1V to 4.9V @ 1 kHz.

4: V_DD=5V_P-P±500 mV @ 1 kHz, see test circuit Figure 3-3.

5: Maximum clock frequency specification must be met.

V_REF= 400 mV, V_IN= 0.1V to 4.9V @ 1 kHz

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

8: For slow sample rates, see Section 6.2.1 for limitations on clock frequency.
