Converter Electrical Characteristics

The following specifications apply after calibration for VA = VTH = VC = +1.2VDC, VO = V25 = +2.5VDC, VIN FSR (a.c. coupled) =

Default ECM setting, CL = 10 pF, Differential a.c. coupled Sinewave Input Clock, fCLK = 2.5 GHz at 0.5VP-P with 50% duty

cycle, REXT = 3600Ω ±0.1%, RTRIM = 3600Ω ±0.1%, Analog Signal Source Impedance = 100Ω Differential, after calibration.

Boldface limits apply for TA = TMIN to TMAX. All other limits TA = 25°C, unless otherwise noted.

Sample

(1)

The analog inputs are protected as shown below. Input voltage magnitudes beyond the Absolute Maximum Ratings may damage this

device.

(2)

To ensure accuracy, it is required that VA, VTH, VC, V25, and VO be well bypassed. Each supply pin must be decoupled with separate

bypass capacitors.

(3)

Typical figures are at TA = 25°C, and represent most likely parametric norms. Test limits are ensured to AOQL (Average Outgoing

Quality Level).

(4)

Calculation of Full-Scale Error for this device assumes that the actual reference voltage is exactly its nominal value. Full-Scale Error for

this device, therefore, is a combination of Full-Scale Error and Reference Voltage Error. See Figure 2. For relationship between Gain

Error and Full-Scale Error, see Specification Definitions.
