MAX2034 is a four-channel, low-power, ultra-low-noise preamplifier designed for ultrasound and medical instrumentation applications.
The MAX2034 is a four‑channel, ultra‑low‑noise preamplifier designed for ultrasound and medical instrumentation. Each channel provides a single‑ended input, differential output, a highly accurate 19 dB fixed gain, and a -3 dB bandwidth of 70 MHz. The device features digitally programmable input impedance (50 Ω, 100 Ω, 200 Ω, 1 kΩ) and integrated input clamping for fast overload recovery.
The part is offered in a 48‑pin thin QFN‑EP package (7 mm × 7 mm) with options for lead‑free and tape‑and‑rewind packaging. Electrical characteristics include a supply voltage of 4.75 V–5.25 V, low power dissipation of 58 mW per channel, and an ultra‑low noise figure of 2.2 dB at 200 Ω source impedance. Ordering information, absolute maximum ratings, and detailed pin descriptions are provided in the document.
