3 / 16 page CS5466 DS659F1 3 1. OVERVIEW The CS5466 is a CMOS monolithic power measurement device with an energy computation engine. The CS5466 combines a programmable gain amplifier, two ∆Σ ADCs, and energy-to-frequency conversion circuitry on a single chip. The CS5466 is designed for energy measurement applications and is optimized to interface to a shunt or current transformer for current measurement, and to a resistive divider or transformer for voltage measurement. The current channel has a programmable gain amplifier (PGA) which provides four full-scale input options. With a single +5 V supply on VA+/AGND, both of the CS5466’s input channels accommodate common-mode plus signal levels be- tween (AGND - 0.25 V) and VA+. The CS5466 has three pulse output pins: E1, E2, and FOUT. E1 and E2 can be used to directly drive a mechanical counter or stepper motor, or interface to a microcontroller. The FOUT pin conveys active (real) power at a pulse fre- quency many times higher than that of the E1 or E2 pulse frequency, allowing for high-speed calibration. |
