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...

Low Power FPD-Link (LVDS) Serializer

The DS90C187 is a Low Power Serializer for portable battery powered application that reduces the size of the RGB interface between the host GPU and the Display.

The DS90C187 Serializer is designed to support dual pixel data transmission between Host and Flat Panel Display up to QXGA 2048×1536@60Hz resolutions. The transmitter converts up to 48 bits (Dual Pixel 24 bit color) of 1.8V LVCMOS data into two channels of 4 data + clock (4D+C) reduced width interface LVDS compatible data streams.

LVDS MEMS Oscillators ±20ppm up to 625MHz

Ecliptek is significantly expanding its LVDS offerings with these four new EMRE oscillator series.
