NOTES

1This is an end-point linearity specification.

2Guaranteed to be monotonic over the full operating temperature range.

3ppm/°C of FSR (FSR = Full Scale Range = VREF-1 LSB.)

4Input Resistance Temperature Coefficient = +300ppm/°C.

5Logic Inputs are MOS gates. Typical input current at +25°C Is less than 10 nA.

6Guaranteed by design.

7From Digital Input to 90% of final analog output current.

8All Digital Inputs “0” or VDD.

9All Digital Inputs VIH or VIL.

10See Timing Diagram.

11Digital Inputs = 0 V to VDD or VDD to 0 V.

12Extrapolated: tS (1/2 LSB) = tPD + 6.2τ where τ = the measured first time con-

stant of the final RC decay.

13All Digital Inputs = 0 V; VREF = +10 V.

Specifications subject to change without notice.

*θJA is specified for worst case mounting conditions, i.e., θJA is specified for

device in socket for cerdip and P-DIP packages; θJA is specified for device

soldered to printed circuit board for SOL and PLCC packages.

CAUTION

1. Do not apply voltages higher than VDD +0.3 V or less than

–0.3 V potential on any terminal except VREF and RFB.

2. The digital control inputs are diode-protected; however,

permanent damage may occur on unconnected inputs from

high energy electrostatic fields. Keep in conductive foam at

all times until ready to use.

3. Use proper antistatic handling procedures.

4. Absolute Maximum Ratings apply to both packaged devices

and DICE. Stresses above those listed under Absolute Maxi-

mum Ratings may cause permanent damage to the device.
