Key Features

  • UHF ASK and FSK modulation in a single transmitter IC
  • 3 V nominal supply with 11 mA maximum supply current for battery efficiency
  • 8-pin TSSOP (PDSO-G8) package for compact PCB integration
  • REACH and RoHS-compliant (e3) halogen-free construction
  • Suitable for industrial ISM-band remote control and sensor telemetry

Applications

The ATA8403C-6AQY66 is used in UHF ISM-band transmitter modules for industrial remote controls, wireless sensor nodes, and remote keyless entry systems operating at 3 V. Its low 11 mA peak supply current and compact TSSOP-8 footprint make it well-suited for coin-cell or AA-battery-powered handheld transmitters with data rates up to several kbps.

Frequently Asked Questions

What modulation schemes does the ATA8403C-6AQY66 support for industrial wireless links?

The ATA8403C-6AQY66 supports both ASK (Amplitude Shift Keying) and FSK (Frequency Shift Keying) modulation in the UHF band, giving designers flexibility to comply with ISM-band regulations at 433 MHz or 868 MHz and to optimize between range and immunity to adjacent-channel interference in industrial environments.

How does the ATA8403C-6AQY66 supply current affect battery life in a handheld remote control?

With a maximum supply current of 11 mA at 3 V and a duty-cycled transmit schedule, a pair of AA batteries (roughly 2500 mAh each) can sustain tens of thousands of button-press transmissions. At 10 ms TX bursts and 1 press per minute, average current drops well below 1 mA, enabling multi-year battery life in typical remote control usage.

Which package does the ATA8403C-6AQY66 use, and how does it simplify PCB layout for a transmitter module?

The ATA8403C-6AQY66 comes in an 8-pin TSSOP package (0.65 mm pitch, body approximately 3 mm x 4.4 mm), providing a small footprint that fits within compact RF module PCBs. The 8-pin count covers power, ground, data input, frequency-setting, and antenna output pins, minimizing external component requirements for a complete transmitter circuit.
