Multiplexer

Description Power Multiplexer - Dual Input -> Single Output Power Switch - Micro-B Connector The Fairchild FPF1320 dual-input single-output power switch is a unique IC that switches a load between two power sources. It behaves as a power multiplexer (or mux), using a digital select signal to determine which of the two 1.5 V to 5.5 V input power rails to connect to the output, and can handle a maximum of 1.5 A while blocking unwanted reverse current from flowing from output to input or between inputs. Each input channel is controlled by an internal MOSFET switch, avoiding the voltage drop that occurs when diodes are used to OR multiple power supplies together.

This AJA 3G/1.5G HD-SDI Multiplexer is an economical, versatile tool that allows you to interconnect dual-link 1.5G SMTPE372M and 3G SMTPE425M. 3GM is bi-directional, which allows a 1.5G to 3G, or 3G dual to 1.5G connection. Furthermore, 3GM's 3G HD-SDI output is now configurable for SMTPE245M type A or B. It can even convert 3G from or to type A or B. This multiplexer also provides a monitor output, which is a single link SMTPE292M 1.5G HD-SDI. It is also compatible with SMTPE259M 270Mb SDI. Additionally, this device is fully equalizing and re-clocking with jitter attenutation, and passes all ancillary data.

Description:   74HCT4051 is a single-pole octal-throw analog switch (SP8T) suitable for use in analog or digital 8:1 multiplexer/demultiplexer applications. The switch features three digital select inputs (S0, S1 and S2), eight independent inputs/outputs (Yn), a common input/output (Z) and a digital enable input (E). When E is HIGH, the switches are turned off. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Features:   Wide analog input voltage range from -5 V to +5 V Complies with JEDEC standard no. 7A Low ON resistance:   80 ohm (typical) at VCC - VEE = 4.5 V   70 ohm(typical) at VCC - VEE = 6.0 V   60 ohm(typical) at VCC - VEE = 9.0 V Logic level translation: to enable 5 V logic to communicate with±5 V analog signals Typical ‘break before make’ built-in ESD protection:   HBM JESD22-A114F exceeds 2000 V   MM JESD22-A115-A exceeds 200 V   CDM JESD22-C101E exceeds 1000 V Multiple package options Specified from -40¿¿¿ to +85¿¿¿ and -40¿¿¿ to +125¿¿¿  Package included: 5 x CJMCU-4051 74HC4051 8 Channel Analog Multiplexer Module

Description: The ADS1232 and ADS1234 are precision 24-bit analog-to-digital converters (ADCs). With an onboard, low-noise programmable gain amplifier (PGA), precision delta-sigma ADC and internal oscillator, the ADS1232/4 provide a complete front-end solution for bridge sensor applications including weigh scales, strain gauges and pressure sensors. The input multiplexer accepts either two (ADS1232) or four (ADS1234) differential inputs. The ADS1232 also includes an onboard temperature sensor to monitor ambient temperature. The onboard, low-noise PGA has a selectable gain of 1, 2, 64, or 128 supporting a full-scale differential input of ±2.5V, ±1.25V, ±39mV, or ±19.5mV. The delta-sigma ADC has 23.5-bit effective resolution and is comprised of a 3rd-order modulator and 4th-order digital filter. Two data rates are supported: 10SPS (with both 50Hz and 60Hz rejection) and 80SPS. The ADS1232/4 can be clocked externally using an oscillator or a crystal. There is also an internal oscillator available that requires no external components. Offset calibration is performed on-demand and the ADS1232/4 can be put in a low-power standby mode or shut off completely in power-down mode. All of the features of the ADS1232/4 are operated through simple pin-driven control. There are no digital registers to program in order to simplify software development. Data are output over an easily-isolated serial interface that connects directly to the MSP430 and other microcontrollers. The ADS1232 is available in a TSSOP-24 package and the ADS1234 is in a TSSOP-28. Both are fully specified from -40°C to +105°C. Features: Complete Front-End for Bridge Sensors Up to 23.5 Effective Bits Onboard, Low-Noise PGA RMS Noise: 17nV at 10SPS (PGA = 128) 44nV at 80SPS (PGA = 128) 19.2-Bit Noise-Free Resolution at Gain = 64 Over 100dB Simultaneous 50Hz and 60Hz Rejection Flexible Clocking: Low-Drift Onboard Oscillator (±3%) Optional External Crystal Selectable Gains of 1, 2, 64, and 128 Easy Ratiometric Measurements—External Voltage Reference up to 5V Selectable 10SPS or 80SPS Data Rates Two-Channel Differential Input with Built-In Temperature Sensor (ADS1232) Four-Channel Differential Input (ADS1234) Simple Serial Digital Interface Supply Range: 2.7V to 5.3V -40°C to +105°C Temperature Range Applications: Weigh Scales Strain Gauges Pressure Sensors Industrial Process Control Package included: 10 x 24bit Analog-to-Digital Converter Board
