MAX2769 is a high-performance, low-cost single-chip GPS receiver that supports GPS, GLONASS and Galileo navigation satellite systems
The MAX2769 is a single‑conversion, low‑IF GNSS receiver that supports GPS, GLONASS, and Galileo on a single chip. Designed on Maxim's low‑power SiGe BiCMOS process, it integrates the complete receiver chain, including dual‑input LNA, mixer, filters, PGA, VCO, fractional‑N synthesizer, crystal oscillator, and multibit ADC.
The document provides detailed electrical specifications, typical operating characteristics, low‑power mode settings, layout recommendations, and package information for the 28‑pin thin QFN (5 mm × 5 mm) device, enabling designers to implement a compact, high‑performance GPS solution.
| Supply Voltage | 2.7 V – 3.3 V |
|---|---|
| Supply Current (Idle) | 1.5 mA |
