Linear Technology has announced the LTC6102, the most precise high side current sense amplifier available. Maximum input offset voltage of the LTC6102 is only 10uV and it can accept differential sense voltages up to 2V. The resulting 106dB of dynamic range allows the LTC6102 to resolve micro-amps from amps of current. Compared to other current sense amplifiers, the dramatically lower offset of the LTC6102 allows for proportionately lower sense re...

Texas Instruments has introduced what is says is the industry’s smallest (SC70 package) low-power, resistor-programmable temperature switch that operates over the largest supply voltage range. The TMP300 allows for simple temperature monitoring and control. The tiny size of the device makes it an attractive option for power supply systems, DC/DC modules, thermal monitoring and electronic protection systems.

Texas Instruments has introduced a 16-bit, single-channel, buffered voltage-output digital-to-analog converter (DAC) with excellent linearity (1 LSB max INL), low noise (24 nV/rtHz) and fast settling time (5.0 uS). Combined with low-power consumption (5mW), the DAC8881 is an attractive option for industrial process control, automatic test equipment, data acquisition systems and communications applications.

Texas Instruments has introduced a family of integrated wideband variable gain amplifiers. The new devices’ unique architecture provides designers with a highly flexible combination of bandwidth, gain and analog input voltage to address design challenges of differential line receivers and equalizers, pulse shaping, continuously variable gain and attenuation stages, automatic gain control (AGC) and voltage tunable filters. These applications...

Linear Technology has introduced the LTC2630, a family of 12-bit, 10-bit and 8-bit digital-to-analog converters (DACs) in tiny 2.1mm x 2mm SC70 packages - the smallest available DACs with an internal reference. The LTC2630 offers the choice of an internal 2.5V or 4.096V 10ppm/°C full-scale reference, providing nearly a 50% board space reduction over competing DACs with an internal reference. These single voltage output DACs achieve 12-bit DC per...

Microchip has announced the MCP4725 DAC, said to be the industry’s first DAC to combine 12-bit resolution, and an integrated EEPROM in a miniature, 6-pin SOT-23 package. The low-power, single-channel DAC has a buffered voltage output and is ideal for space-constrained and battery-powered applications found in a variety of markets.

Linear Technology has announced the LTC6400-20 and LTC6401-20, ADC drivers that achieve unprecedented performance on a single 3V supply. These fully differential amplifiers include gain setting resistors, simplifying the challenge of driving the highest performance high-speed ADCs. The LTC6400-20 provides a fixed gain of 20dB with -93dBc third-order intermodulation distortion (IMD3) performance and noise figure of 6.5dB for a 140MHz input frequen...

Linear Technology has introduced the LTC2450, a 16-bit delta sigma analog-to-digital converter (ADC) in an ultra-tiny 2mm x 2mm DFN package that enables performance upgrades to lower resolution systems. Designers of portable and space-constrained applications typically trade off space with performance, leading to use of microcontrollers with internal ADCs or lower resolution ADCs with preamplifier circuitry. These designs are typically complex an...
