AD7988 / LTC3335 / LTP5901 / LT6656 / LTC2063 Wireless Current Sensing Combinations

ADI and Linear Technology offer a wireless current sensing solution that combines great products from each company, including the AD7988, LTC3335, LTP5901, LT6656, and LTC2063

Image of ADI and LTC's Wireless Current Sensing Combinations ADI and Linear Technology (now part of ADI) offer a wireless current sensing solution that combines great products from each company. The AD7988 is a 16-bit analog-to-digital converter (ADC) that has sampling rates of 100 k and 500 k per second. This ADC has a 2.5 V supply with 1.8 V, 2.5 V, 3 V, and 5 V logic interface. The AD7988 has available multiple serial interfaces such as SPI-/QSPI™, MICROWIRE™, and DSP. The LTP5901 is a transceiver that uses 802.15.4 wireless standard. This 2.4 GHz transceiver uses 2.1 V to 3.76 V input, a low 4.5 mA of current receiving, and 5.4 mA to 9.7 mA of current transmitting.

The LT6656 are a series of 1 µA voltage references with various voltage input and output options to choose from. The LTC2062 is 2 µA supply current zero drift operational amplifier (op amp). These op amps can be used as a signal chain building block. The LTC3335 is a nanopower buck (down)-boost (up) regulator that is designed with a coulomb counter for battery powered applications. These parts coming in a variety of packages and temperature ranges. This wireless current sensing solution from Analog Devices is ideal for portable, handheld, wireless, scientific, and medical applications.
