The MAX410/MAX412/MAX414 single/dual/quad op amps set a new standard for noise performance in high-speed, low-voltage systems. Input voltage-noise density is guaranteed to be less than 2.4nV per root-Hz at 1kHz. A unique design not only combines low noise with ±5V operation, but also consumes 2.5mA supply current per amplifier. Low-voltage operation is guaranteed with an output voltage swing of 7.3VP-Pinto 2kΩ from ±5V supplies. The MAX410/MAX412/MAX414 also operate from supply voltages between ±2.4V and ±5V for greater supply flexibility.Unity-gain stability, 28MHz bandwidth, and 4.5V/µs slew rate ensure low-noise performance in a wide variety of wideband and measurement applications. The MAX410/MAX412/MAX414 are available in DIP and SO packages in the industry-standard single/dual/quad op amp pin configurations. The single comes in an ultra-small TDFN package (3mm x 3mm).ApplicationsAutomatic Test Equipment (ATE)Bridge Signal ConditioningDisplays: Industrial, Front Panel, and InstrumentationHigh-Quality Audio AmplifiersIndustrial: Process Measurement and ControlInfrared DetectorsLow-Noise Frequency SynthesizersPanel MetersPower MetersProgrammable Logic Controllers (PLCs)Ultra Low-Noise Instrumentation Amplifiers

The MAX41461/MAX41462 is a UHF sub-GHz ISM/SRD transmitter is designed to transmit On-Off Keying (OOK) or Amplitude-Shift Keying (ASK) data in the 286MHz to 960MHz frequency range. It integrates a fractional phase-locked-loop (PLL), so a single, low-cost crystal can be used to generate commonly used world-wide sub-GHz frequencies. The fast response time of the PLL allows for frequency-hopping spread spectrum protocols for increased range and security. The chip also features preset modes with pin-selectable frequencies so that only one wire is required for external microcontroller interface. The only frequency-dependent components required are for the external antenna matching network. Optionally, the device can be put into programmable mode and programmed using an I2C interface. The crystal-based architecture of the MAX41461/MAX41462 eliminates many of the common problems with SAW-based transmitters by providing greater modulation depth, faster frequency settling, higher tolerance of the transmit frequency, and reduced temperature dependence. A clock-out signal at 800kHz is also provided.The MAX41461/MAX41462 provides output power up to +13dBm into a 50Ω load while drawing < 8mA (Manchester coded). The output load can be adjusted to increase power up to +16dBm, and a PA boost mode can be enabled at frequencies above 850MHz to compensate for losses. The PA output power can also be controlled using programmable register settings in I2C mode.The MAX41461/MAX41462 also features single-supply operation from +1.8V to +3.6V. The device has an auto-shutdown feature to extend battery life and a fast oscillator wake-up with data activity detection.The MAX41461/MAX41462 is available in a 10-pin μMAX package and is specified over the -40°C to +105°C extended temperature range. The MAX41461/MAX41462 has an ESD rating of 2.5kV HBM.Design Solution: How to Maximize the Wireless Power Range of Your UHF Sub-GHz Short-Range Device ›ApplicationsAutomatic Meter Reading (AMR)Building Automation and SecurityGarage Door Openers (GDO)Internet of Things (IoT)Radio Control ToysRemote and Passive Keyless Entry (RKE/PKE)Tire Pressure Monitoring Systems (TPMS)Wireless Sensors and Alarms
