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.
