Microchip Technology Inc., a provider of microcontroller, mixed-signal, analog and Flash-IP solutions, announced the MCP9600—the world’s first thermocouple-conditioning integrated circuit to combine precision instrumentation, a precision temperature sensor and a precision, high-resolution analog-to-digital converter (ADC), in addition to a math engine preprogrammed with the firmware to support a broad range of standard thermocouple types (K, […]
Data Converters
One chip, any temperature sensor — IC digitizes all temp. sensors
A chip called the LTC2983 directly digitizes RTDs, thermocouples, thermistors and external diodes with 0.1°C accuracy and 0.001°C resolution. The device combines low-noise and low-offset-buffered ADCs with excitation and control circuits for each type of sensor. The chip precisely measures absolute microvolt-level signals from thermocouples and ratiometric resistance measurements from RTDs and thermistors, linearizes the results […]
High-speed a/d converters hit 200 msps
Microchip announced two families of new high-speed A/D converters in the MCP37DX1-200 and MCP372X1-200 families. These families feature 12-, 14- and 16-bit pipelined A/D converters with a maximum sampling rate of 200 Mega samples per second (Msps). The 14- and 16-bit devices feature high accuracy of over 74 dB Signal-to-Noise Ratio (SNR) and over 90 […]
100-V forward converter outputs regulated 12 V without optocoupling
Linear Technology Corporation announces the LT8310, a primary-side synchronous forward controller. The LT8310 operates over an input voltage range of 6V to 100V, is targeted for power levels up to 200W and provides a drive signal for secondary-side synchronous rectification to improve efficiency. Output voltage regulation of ±8% can be attained without the use of […]
2kVAC Isolated 1.5W low noise μModule converters in 9mm x 11.25mm x 4.92mm BGA package are UL60950 recognized
Linear Technology Corporation introduces the LTM8057 and LTM8058, 1.5W output μModule® (micromodule) DC/DC converters with 2kVAC galvanic isolation (production tested to 3kVDC) in a 9mm x 11.25mm x 4.92mm BGA (ball grid array) package. The LTM8057 and LTM8058 include an isolated transformer, control circuitry, power switches and a modest amount of input and output capacitance. […]
1-Wire Thermocouple-to-Digital Converters
The MAX31850/MAX31851, cold-junction-compensated, 1-Wire thermocouple-to-digital converters were introduced today. The devices achieve ±2.0°C accuracy (not including sensor nonlinearity) while integrating all of the functions required for a complete (thermocouple-to-digital solution). Additionally, the MAX31850/MAX31851’s 1-Wire interface allows multiple sensor locations to communicate and draw power over a single data line, greatly simplifying wiring requirements. Designers can […]
