The MAX1126 quad analog‑to‑digital converter features fully differential inputs, a pipelined architecture, and digital error correction. It operates from a 1.7 V to 1.9 V single supply, consumes only 563 mW in normal mode and 1.5 mW in shutdown, and delivers 69.9 dB SNR at 5.3 MHz.
Key features include four 12‑bit channels with LVDS/SLVS outputs, a flexible reference structure (internal 1.24 V bandgap or external), a small 68‑pin QFN package, and extensive timing and electrical specifications for high‑speed board designs.
