MAX1003 Datasheet Low-power / 90msps / Dual 6-bit Adc

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-1236; Rev 0; 6/97 KIT ATION EVALU E L B AVAILA Low-Power, 90Msps, Dual 6-Bit.

General Description

The MAX1003 is a dual, 6-bit analog-to-digital converter (ADC) that combines high-speed, low-power operation with a user-selectable input range, an internal reference, and a clock oscillator.

The dual parallel ADCs are designed to convert in-phase (I) and quadrature (Q) analog signals into two 6-bit, offset-binary-coded digital outputs at sampling rates up to 90Msps.

The ability to directly interface with baseband I and Q signals makes the MAX1003 ideal for use in direct-broadcast satellite, VSAT, and QAM16 demodulation applications.
