MAX7034AUI/V+T

RF Receivers Overview

The MAX7034AUI/V+T is a fully integrated low-power CMOS superheterodyne receiver designed for amplitude-shift-keyed (ASK) data reception in the 300MHz to 450MHz frequency range. It features an RF sensitivity of -114dBm and supports maximum data rates up to 66kbps. The device operates from a single +3.3V/+5.0V supply with a typical operating current of 7.2mA. It includes a low-noise amplifier, differential mixer, on-chip PLL with VCO, 10.7MHz IF limiting amplifier with RSSI, and analog baseband circuitry. The component is housed in a 28-TSSOP package and specified over an automotive temperature range of -40°C to +125°C.

RF Receivers Feature Summary

• Integrates a low-noise amplifier, image-rejection mixer, phase-locked loop with voltage controlled oscillator, and 10.7MHz IF limiting amplifier with received-signal-strength indicator.
• Provides excellent receive sensitivity over temperature with built-in 44dB RF image rejection.
• Features a low-current power-down mode for efficient power cycling and a rapid startup time.
• Supports selectable image-rejection center frequencies and selectable frequency ratios.

RF Receivers Applications

• Automotive Remote Keyless Entry
• Security Systems
• Garage Door Openers

RF Receivers Procurement Notes

Verify that the specific suffix 'V' indicates the extended automotive temperature rating (-40°C to +125°C) as defined by the manufacturer's nomenclature. Confirm the tape-and-reel packaging designation matches the required production volume. Ensure the order specifies the correct supply voltage requirements relative to the selected operating mode. Cross-reference the RoHS compliance status with current regulatory standards for the target market.

RF Receivers Selection Notes

Select this component for applications requiring high sensitivity in the 315MHz or 433.92MHz bands with minimal external components. Consider the 28-TSSOP package dimensions for PCB layout constraints. Evaluate the power consumption against battery life requirements, noting the low standby current capability. Ensure the system design accommodates the 10.7MHz intermediate frequency filtering requirements inherent to the superheterodyne architecture.

RF Receivers Part Context

This part belongs to the MAX7034 family of ASK receivers manufactured by Analog Devices Inc./Maxim Integrated. It is specifically tailored for cost-sensitive and power-sensitive markets, including automotive and consumer electronics. The device simplifies radio design by integrating most RF and baseband functions onto a single CMOS chip, reducing bill-of-materials complexity compared to discrete solutions.
