MAX14803ALow-Charge-Injection, 16-Channel, High-Voltage Analog Switches | Analog Switches, Multiplexers, Demultiplexers | 1 | Unknown | The MAX14802/MAX14803/MAX14803A provide high-voltage switching on 16 channels for ultrasonic imaging and printer applications. The devices utilize HVCMOS process technology to provide 16 high-voltage low-charge-injection SPST switches, controlled by a digital interface. Data is clocked into an internal 16-bit shift register and retained by a programmable latch with enable and clear inputs. A power-on reset function ensures that all switches are open on power-up.The MAX14802/MAX14803/MAX14803A operate with a wide range of high-voltage supplies including VPP/VNN= +100V/-100V, +200V/0V, or +40V/-160V. The digital interface operates from a separate +2.7V to +5.5V VDDsupply. Digital inputs DIN, CLK, active-low LE, and CLR operate on the VDDsupply voltage.The MAX14803/MAX14803A provide integrated 35kΩ bleed resistors on each switch terminal to discharge capacitive loads. The MAX14802/MAX14803/MAX14803A provide integrated clamping diodes for overvoltage protection against positive overshoot.The MAX14802 is available in a 48-pin LQFP package and is specified for commercial 0°C to +70°C and extended -40°C to +85°C temperature ranges.The MAX14803 is available in a 48-pin LQFP package and is specified for the commercial 0°C to +70°C temperature range.The MAX14803A is available in the 110-bump wafer level package (WLP) and is specified at the -40°C to +85°C temperature range.ApplicationsPrintersUltrasound Imaging |

MAX14815Octal 5-Level Pulser with T/R Switch and Embedded Beamforming | Evaluation and Demonstration Boards and Kits | 3 | Active | The MAX14815 is a highly integrated, octal 5-level, high-voltage ultrasound transmitter (pulser).The pulser generates high-frequency HV bipolar pulses for driving piezoelectric transducers in ultrasound systems from two independent pairs of HV supplies. Each channel can transmit up to 200VPPwith up to 2A current capability and features an integrated 2A active clamp (Return to Zero). The current capability can be programmed down to 0.4A.The pulser can be controlled using embedded digital resources (SRAM and state machine) that can be used to support transmit beamforming, resulting in dramatic savings in the number of interconnects and FPGA I/Os. The embedded digital resources are programmed via a high-speed serial interface and support sophisticated transmit techniques like PWM for burst shaping and apodization for beam shaping.Alternatively, the device can be controlled in a conventional manner by an external digital source (FPGA) through dedicated CMOS logic inputs.The MAX14815 also features eight independent low-noise, low-impedance active T/R switches.The T/R switches can be externally configured to support receive multiplexing in which a fewer number of receive channels than transmit channels are used.The MAX14815 is packaged in a 10mm x 10mm TQFN package.ApplicationsHV Transducers MEMS DriversUltrasound Industrial Applications (NDT)Ultrasound Medical Imaging |
MAX14819Dual IO-Link Master Transceiver with Integrated Framers and L+ Supply Controllers | Evaluation Boards | 4 | Active | The MAX14819/MAX14819A low-power, dual-channel, IO-Link®master transceiver with sensor/actuator power- supply controllers is fully compliant with the latest IO-Link and binary input standards and test specifications, IEC 61131-2, IEC 61131-9 SDCI, and IO-Link 1.1.3. This master transceiver also includes two auxiliary digital input (DI_) channels.The MAX14819/MAX14819A is configurable to operate either with external UARTs or using the integrated fram- ers on the IC.To ease selection of microcontroller, the master transceiver features frame handlers with UARTs and FIFOs. These are designed to simplify time critical control of all IO-Link M-sequence frame types. The MAX14819/MAX14819A also features autonomous cycle timers, reducing the need for accurate controller timing. Integrated establish-communication sequencers also simplify wake-up management.The device message response delay on the MAX14819A can be disabled when using the frame handler and the MAX14819A features higher L+ thresholds than the MAX14819. The MAX14819A receivers also feature increased high-frequency signal isolation compared to the MAX14819.The MAX14819/MAX14819A integrates two low-power sensor supply controllers with advanced current limiting, reverse current-blocking, and reverse polarity protection capability to enable low-power robust solutions.The MAX14819/MAX14819A is available in a 48-pin (7mm x 7mm) TQFN package and is specified over the extended -40°C to +125°C temperature range.ApplicationsIO-Link GatewaysIO-Link Master Systems |
