The MAX202E-MAX213E, MAX232E, and MAX241E are a family of RS-232 and V.28 transceivers with high ±15kV ESD HBM protection and integrated charge pump circuitry for single +5V supply operation. The various combinations of features are outlined in theSelector Guide. The drivers and receivers for all ten devices meet all EIA/TIA-232E and CCITT V.28 specifications at data rates up to 120kbps when loaded.The MAX211E/MAX213E/MAX241E are available in 28-pin SO and SSOP packages. The MAX202E/MAX232E come in 16-pin TSSOP, narrow SO, wide SO, and DIP packages. The MAX203E comes in a 20-pin DIP/SO package, and needs no external charge-pump capacitors. The MAX205E comes in a 24-pin wide DIP package, and also eliminates external charge-pump capacitors.ApplicationsBattery-Powered EquipmentHandheld EquipmentPortable Diagnostics Equipment

The MAX2045/MAX2046/MAX2047 low-cost, fully integrated vector multipliers alter the magnitude and phase of an RF signal. Each device is optimized for the UMTS (MAX2045), DCS/PCS (MAX2046), or cellular/GSM (MAX2047) frequency bands. These devices feature differential RF inputs and outputs.The MAX2045/MAX2046/MAX2047 provide vector adjustment through the differential I/Q amplifiers. The I/Q amplifiers can interface with voltage and/or current digital-to-analog converters (DACs). The voltage inputs are designed to interface to a voltage-mode DAC, while the current inputs are designed to interface to a current-mode DAC. An internal 2.5V reference voltage is provided for applications using single-ended voltage DACs. The parts are ideal for CDMA, multicarrier CDMA, cdma2000®, and WB-CDMA applications.The MAX2045/MAX2046/MAX2047 operate from a 4.75V to 5.25V single supply. All devices are offered in a compact 5mm x 5mm, 32-lead thin QFN exposed-paddle package.The MAX2045/MAX2046/MAX2047 evaluation kits help speed designs.

The MAX20404/MAX20405/MAX20406/MAX20406EICs are tiny, low EMI emission, synchronous Silent Switcher®buck converters with integrated high-side and low-side switches. The ICs are designed to deliver up to 6A with wide input voltages range from 3V to 36V. Voltage quality can be monitored by observing the PGOOD signal. The MAX20404/MAX20405/MAX20406/MAX20406E can operate in dropout by running at 99% duty cycle making it ideal for automotive and industrial applications.The MAX20404/MAX20405/MAX20406/MAX20406E offer programmable or fixed output voltages of 5V and 3.3V. Frequency is internally fixed at 2.1MHz (or 400KHz or 3MHz) which allows for small external components, reduced output ripple, and guarantees no AM interference. MAX20404/MAX20405/MAX20406/MAX20406E automatically enter skip mode at light loads with ultra-low quiescent current of 10µA at no load. This family of products (including the MAX20408/10) offers a pin-to-pin compatible offering from 4A to 10A in a single-phase configuration, and up to 20A in a dual-phase configuration. This devices have also been optimized for dual-phase operation with very high current sharing accuracy. These devices can be ordered with spread-spectrum frequency modulation designed to minimize EMI-radiated emissions due to the modulation frequency.The MAX20404/MAX20405/MAX20406/MAX20406E are available in a small 3.5mm x 3.75mm 17-pin FC2QFN package and uses very few external components.ApplicationsAutomotiveInfotainment SystemsADAS and Other Safety-Critical ApplicationsIndustrialHigh-Voltage DC-DC Converters
