Description
The CS5460 is a highly integrated ∆Σ Analog-to-Digital
Converter (ADC) which combines two ∆Σ ADCs, high
speed power calculation functions, and a serial interface
on a single chip. It is designed to accurately measure
and calculate: Energy, Instantaneous Power, IRMS, and
VRMS for single phase 2 or 3-wire power meter applica-
tions. The CS5460 interfaces to a low cost shunt or
transformer to measure current, and resistive divider or
transformer to measure voltage. The CS5460 features a
bi-directional serial interface for communication with a
micro-controller and a fixed-width programmable fre-
quency output that is proportional to energy. The product
is initialized and fully functional upon power-up, and in-
cludes facilities for system-level calibration under control
of the user program.

Notes: 8. All voltages with respect to ground.
9. VA+ and VA- must satisfy {(VA+) - (VA-)} < +6.0 V.
10. VD+ and VA- must satisfy {(VD+) - (VA-)} < +6.0 V.
11. Applies to all pins including continuous over-voltage conditions at the analog input (AIN) pins.
12. Transient current of up to 100 mA will not cause SCR latch-up. Maximum input current for a power
supply pin is ±50 mA.
13. Total power dissipation, including all input currents and output currents.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
