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 refer- ence, and a clock oscillator.
The MAX1003 is a dual, 6-bit analog-to-digital converter (ADC) designed for high-speed, low-power applications. It combines an internal reference and clock oscillator with user-selectable input ranges to convert in-phase (I) and quadrature (Q) analog signals into digital outputs at sampling rates up to 90Msps.
The device features two matched ADCs with true differential inputs and a -0.5dB analog bandwidth of 55MHz. It operates with +5V analog and +3.3V digital supplies, making it compatible with standard microprocessors and DSPs. The MAX1003 is packaged in a 36-pin SSOP case.
| Resolution | 6-bit |
|---|---|
| Maximum Sample Rate | 90Msps per ADC |
| Analog Input Bandwidth | -0.5dB at 55MHz |
| Power Dissipation | 350mW |
| Effective Number of Bits (20MHz input) | 5.85 ENOB |
| Operating Temperature Range | 0°C to +70 °C |
| Package Type | 36-pin SSOP |
The input amplifiers feature user-programmable input full-scale ranges of 125mVp-p, 250mVp-p, or 500mVp-p.
Matching performance between input channels is typically better than 0.1dB gain, 1/4LSB offset, and 0.5° phase.
The device operates with +5V analog and +3.3V digital supplies.
