ADS131M04 4-Channel, Simultaneously-Sampling, 24-Bit, Delta-Sigma ADC

1 Features

3 Description

•

4 simultaneously sampling differential inputs

Programmable data rate up to 32 kSPS

Programmable gain up to 128

The ADS131M04 is a four-channel, simultaneously-

sampling, 24-bit, delta-sigma (ΔΣ), analog-to-digital

converter (ADC) that offers wide dynamic range, low

power, and energy-measurement-specific features,

making the device an excellent fit for energy metering,

power metrology, and circuit breaker applications. The

ADC inputs can be directly interfaced to a resistor-

divider network or a power transformer to measure

voltage or to a current transformer, shunt, or a

Rogowski coil to measure current.

Noise performance:

– 102-dB dynamic range at gain = 1, 4 kSPS

– 80-dB dynamic range at gain = 64, 4 kSPS

Total harmonic distortion: –100 dB

High-impedance inputs for direct sensor

connection:

•

– 330-kΩ input impedance for gains of

1, 2, and 4

– 1-MΩ input impedance for gains of

8, 16, 32, and 64

Programmable channel-to-channel phase delay

calibration:

– 244-ns resolution, 8.192-MHz f_CLKIN

Current-detect mode allows for extremely low

power tamper detection

Fast startup: first data within 0.5 ms of supply

ramp

Integrated negative charge pump allows input

signals below ground

The individual ADC channels can be independently

configured depending on the sensor input. A low-

noise, programmable gain amplifier (PGA) provides

gains ranging from 1 to 128 to amplify low-level

signals. Additionally, this device integrates channel-to-

channel phase calibration and offset and gain

calibration registers to help remove signal-chain

errors.

•

A low-drift, 1.2-V reference is integrated into the

device reducing printed circuit board (PCB) area.

Cyclic redundancy check (CRC) options can be

individually enabled on the data input, data output,

and register map to ensure communication integrity.

•

Crosstalk between channels: –120 dB

Low-drift internal voltage reference

Cyclic redundancy check (CRC) on

communications and register map

2.7-V to 3.6-V analog and digital supplies

Low power consumption: 3.3 mW at 3-V AVDD

and DVDD

The complete analog front-end (AFE) is offered in a

20-pin TSSOP or leadless 20-pin WQFN package and

is specified over the industrial temperature range of

–40°C to +125°C.
