The MAX1437B is an 8-channel, 12-bit analog-to-digital converter (ADC) optimized for low-power and high-dynamic performance in medical imaging instrumentation and digital communications applications.
The MAX1437B is an octal, 12‑bit analog‑to‑digital converter optimized for low‑power, high‑dynamic‑performance applications such as medical imaging and multichannel communications. It operates from a 1.8 V supply, consumes 96 mW per channel, and delivers up to 70.2 dB SNR at 5.3 MHz.
The device features fully differential inputs, an on‑chip PLL for LVDS clock generation, selectable LVDS/SLVS outputs, and a flexible reference architecture that supports an internal 1.24 V bandgap or an external reference. It is offered in a 68‑pin TQFN‑EP package (10 mm × 10 mm × 0.8 mm) rated for –40 °C to +85 °C operation.
