Accurate to 0.1% over a 1000-to-1 dynamic range, they surpass the requirements of the IEC 62053-2x standards. They measure active and apparent energy, as well as rms voltage and current. The ADE7169 also measures reactive energy, with less than 0.5% error over a 1000-to-1 dynamic range. The data, provided in energy-measurement units, is ready for energy billing and other uses. In antitamper mode, the reactive power accumulated depends on the sign of the active power. Operating with a single 3.3-V supply, the ADE7166/69 consume 4 mA in normal mode, 3.2 mA in battery mode, and 1.5 μA in sleep mode. Available in 64-lead LQFP packages, they are specified from –40°C to +85°C and priced from $2.62/$3.18 in 1000s.

24-bit, 192-kHz Codec includes PLL, four ADCs, and eight DACs
The AD1937 high-performance, single-chip codec provides four differential-input ADCs and eight differential-output DACs. The ADCs specify 105-dB dynamic range (DR) and –96-dB total-harmonic-distortion-plus-noise (THD+N); and the DACs specify 112-dB DR and –94-dB THD+N.
