4-Bit, 25 MSPS, Flash A/D Converter

Features

Description

• CMOS Low Power (Typ) . . . . . . . . . . . . . . . . . . . 35mW

The Intersil HI3304 is a CMOS parallel (FLASH) analog-to-

digital converter designed for applications demanding both

low-power consumption and high speed digitization. Digitiz-

ing at 25MHz, for example, requires only about 35mW.

• Parallel Conversion Technique

• Single Power Supply Voltage . . . . . . . . . . . . 3V to 7.5V

• Sampling Rate at 5V Supply . . . . . . . . . . . . . . . . . 25MHz

The HI3304 operates over a wide, full-scale signal input volt-

age range of 0.5V up to the supply voltage. Power consump-

tion is as low as 10mW, depending upon the clock frequency

selected.

• 4-Bit Latched Three-State Output with Overflow and

Data Change Outputs

• Maximum Nonlinearity. . . . . . . . . . . . . . . . . . . . / LSB

• Inherent Resistance to Latch-Up

Sixteen paralleled auto-balanced voltage comparators mea-

sure the input voltage with respect to a known reference to

produce the parallel-bit outputs in the HI3304. Fifteen com-

parators are required to quantize all input voltage levels in

this 4-bit converter, and the additional comparator is

required for the overflow bit. A data change pin indicates

when the present output differs from the previous, thus

allowing compaction of data storage.

• Bipolar Input Range with Optional Second Supply

• Input Bandwidth (Typ). . . . . . . . . . . . . . . . . . . . . 40MHz

• Linearity (INL, DNL):

- HI3304JIP . . . . . . . . . . . . . . . . . . . . . . . . . . ±0.25 LSB

- HI3304JIB . . . . . . . . . . . . . . . . . . . . . . . . . . ±0.25 LSB

• Sampling Rate:
