ELECTRICAL SPECIFICATIONS (CONTINUED)

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

TA = -40°C to +85°C (Note 7). Conversion speed (FSAMPLE) is 100 ksps with FCLK = 21*FSAMPLE

Conditions

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

8: For slow sample rates, see Section 5.2 “Driving the Analog Input” for limitations on clock frequency.

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