No sample-and-hold per channel (ratio 0:6) — each differential input has its own modulator, so the six voltage or current waveforms are captured at the same instant without inter-channel phase delay. That matters for polyphase power calculation where the voltage and current vectors must be aligned to compute real power correctly. ## Supply flexibility and temperature grade Analog supply runs from 2.4 V to 3.6 V; the digital interface accepts 1.65 V to 3.6 V independently. That means the ADC core can operate at 3.3 V while the SPI bus talks directly to a 1.8 V host controller without an external level shifter. The -40°C to +125°C operating range covers the full industrial and automotive under-hood ambient — a motor-drive control board seeing 105°C near the IGBTs still has margin. Reference can be external or internal — the on-chip bandgap reference is trimmed and stable over temperature, so a ratiometric measurement (e.g., a shunt resistor referenced to the same supply) needs no external reference IC. For absolute accuracy, an external precision reference can override the internal one via the REFIN pin. ## Package and layout Housed in a 32-pin WFQFN with exposed pad (4x4 mm body). The thermal pad must be soldered to a PCB copper plane to achieve the rated thermal performance — the datasheet recommends a 2x2 array of 0.3 mm vias under the pad to conduct heat to the inner ground plane. The 0.5 mm pitch QFN demands careful solder-paste stencil design; a 4-layer board with solid ground pour under the package is the standard approach for this footprint.","metaTitle":"Texas Instruments ADS131M06IRSNR 6-Ch 24-Bit 32kSPS","metaDescription":"TI ADS131M06IRSNR 6-channel simultaneous-sampling sigma-delta ADC, 24-bit, 32 kSPS, PGA, SPI, -40 to +125°C, 32-QFN.
