SAR ADC with SPICE Model

Texas Instruments Incorporated, today introduced a successive-approximation-register (SAR) analog-to-digital converter (ADC) with a downloadable TINA TI SPICE model, enabling system designers to simulate and characterize the full analog signal chain in software for the first time. The model is available for the new 12-bit, 1-MSPS, 8-channel ADS8028, a highly-integrated SAR ADC featuring a low-drift internal voltage reference, wide external analog voltage reference range, wide analog and...

High-Side Voltage Measurement IC

The INA3221 is a three-channel, high-side current and bus voltage monitor with an I2C interface. The INA3221 monitors both shunt voltage drops and bus supply voltages in addition to having programmable conversion times and averaging modes for these signals. The INA3221 offers both critical and warning alerts to detect multiple programmable out-of-range conditions for each channel.

The INA3221 senses current on buses that can vary from 0 V to +26 V. The device is powered from a single +2.7-V...

4.25 kVPEAK Isolated Amplifier for e-Metering

The AMC1100 is a precision isolation amplifier with an output separated from the input circuitry by a silicon dioxide (SiO2) barrier that is highly resistant to magnetic interference. This barrier has been certified to provide galvanic isolation of up to 4250 VPEAK, according to UL1577 and IEC60747-5-2. Used in conjunction with isolated power supplies, this device prevents noise currents on a high common-mode voltage line from entering the local ground and interfering with or damaging...

50-W Stereo Class-D Audio Amp

The TPA31xxD2 series are stereo efficient, digital amplifier power stage for driving speakers up to 100W/2Ω in mono. The high efficiency of the TPA3130D2 allows it to do 2×15W without external heat sink on a single layer PCB. The TPA3118D2 can even run 2×30W/8Ω without heat sink on a dual layer PCB. If even higher power is needed the TPA3116D2 does 2×50W/4Ω with a small heat-sink attached to its top side PowerPad. All three devices share the same footprint enabling a single PCB to be used...

4 Ch 16-BIT, 125-MSPS ADC

Analog Devices Inc. announced today the addition of a 4-channel high-speed A/D converter to its market-leading data converter product portfolio. The AD9653 A/D converter was designed for medical imaging and communications applications where the combination of high channel density, low power and small size provide systems engineers with greater design flexibility and lower per-channel cost for data conversion. The AD9653 16-bit ADC joins previously-released 12-bit and 14-bit versions to form a...

Schottky Rectifier in Ultra-Small Package

As one of the world’s leading discrete semiconductor suppliers, NXP has released a 1 A Schottky rectifier in the ultra-small 1.0 × 0.6 mm plastic SMD package DFN1006D-2 (SOD882D). The 20 V, 1 A PMEG2010BELD Schottky barrier rectifier delivers a maximum forward voltage of only 430 mV at 1 A forward current combined with low reverse current of 28 μA (typ) at 10 V reverse voltage enabling highly efficient solutions. It’s an excellent choice for mobile, battery-driven, light-weight devices that...

Gallium Nitride Power Transistors

GaN Systems Inc., provider of gallium nitride power switching semiconductors, and Arkansas Power Electronics International Inc. (APEI), developer of state-of-the-art technology for power electronics systems, electronic motor drives, and power electronics packaging, today announced they will collaborate on the development of a high-temperature, high-performance package optimized for gallium nitride transistors and diodes. This co-development is funded in part by the Government of Canada through...

Low Power Differential Amplifier for Precision ADCs

Linear Technology announces the LTC6362, a low power fully differential amplifier that can drive high precision 16- and 18-bit SAR ADCs at only 1mA supply current. With 200µV max input offset voltage and 3.9nV/√Hz input-referred noise, it is well suited for precision industrial and data acquisition applications.

The LTC6362 has an output common-mode pin with a 0.5V to 4.5V range, and 18-bit settling time of 550ns with an 8VP-P output step, making it ideal for driving ADCs such as the...
