The MAX1011 is a 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 ADC converts analog signals into binary-coded digital outputs at sampling rates up to 90Msps. The ability to directly interface with baseband signals makes the MAX1011 ideal for use in a wide range of communications and instrumentation applications. The MAX1011’s input amplifier features a true differential input, a -0.5dB analog bandwidth of 55MHz, and a user-programmable input full-scale range of 125mVp-p, 250mVp-p, or 500mVp-p. With an AC-coupled signal, input offset is typically less than 1/4LSB. Dynamic performance is 5.85 effective number of bits (ENOB) with a 20MHz analog input signal, or 5.7 ENOB with a 50MHz signal. The MAX1011 operates with +5V analog and +3.3V digital supplies for easy interfacing to +3.3V-logic-compatible digital signal processors and microprocessors. It comes in a 24-pin QSOP package.
The MAX1011 is a 6‑bit analog‑to‑digital converter that combines high‑speed operation (up to 90 Msps) with low power dissipation (215 mW). It features a true differential input amplifier with a -0.5 dB bandwidth of 55 MHz and user‑selectable full‑scale ranges of 125 mVp‑p, 250 mVp‑p, or 500 mVp‑p. The device operates from +5 V analog and +3.3 V digital supplies and includes an internal bandgap reference and oscillator.
Key specifications include an ENOB of 5.85 bits at a 20 MHz input, ±1/4 LSB INL/DNL, and a 24‑pin QSOP package. The datasheet provides detailed electrical characteristics, timing diagrams, and layout recommendations for optimal performance in communications and instrumentation applications.
