NOTES

1 A

IN = +VREF.

2 Determined by 3 dB reduction in reconstructed output at 75 MSPS.

3 Under normal operating conditions, the analog input voltages should not

exceed nominal

±2 V operating range, nor the supply voltages (+V

S and –VS),

whichever is smaller.

4 Under normal operating conditions the differential reference voltage may

range from

±0.5 V to ±2 V; +V

REF ≥ –VREF.

5 Output terminated with 100

Ω resistors to –2.0 V.

6 Measured from the leading edge of ENCODE to data out on Bit 1 (MSB).

7 Measured from the trailing edge of ENCODE to data out on Bit 1 (MSB).

8 For full-scale step input, 6-bit accuracy is attained in specified time.

9 Recovers to 6-bit accuracy in specified time, after 150% full-scale input

overvoltage.

10 Measured on Bit 1 (MSB) only.

11 Measured at 50 MSPS encode rate.

12 Analog input frequency = 15 MHz.

13 RMS signal to RMS noise, with 540 kHz analog input signal.

14 Peak-to-peak signal to rms noise, with 540 kHz analog input signal.

15 f

1 = 9.3 MHz, f2 = 7.6 MHz; Encode = 42 MHz.

16 DC to 8.2 MHz noise bandwidth with 3.886 MHz slot.

17 Supply voltage should remain stable within

± 5% for normal operation.

Specifications subject to change without notice.

NOTES

1Absolute maximum ratings are limiting values, to be applied individually, and

beyond which serviceability of the circuit may be impaired. Functional oper-

ability under any of these conditions is not necessarily implied. Exposure to

absolute maximum rating conditions for extended periods may affect device

reliability.

2Under normal operating conditions, the analog input voltages should not

exceed nominal +2 V operating range, nor the supply voltages (+VS and –VS),

whichever is smaller.
