CS5466
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.
