Frequently Asked Questions
What is the resolution and per-channel throughput of the ADS8556IPMR?
The ADS8556IPMR is a 16-bit successive-approximation ADC with six fully differential channels that sample simultaneously at up to 630 kSPS each, giving a 1.26 µs conversion time per channel. INL is specified at ±0.0061% for high-precision data acquisition.
What supply voltage does the ADS8556IPMR require?
The ADS8556IPMR operates from a single analog supply between 4.5 V and 5.5 V (5 V nominal). The on-chip programmable-gain amplifier extends the differential analog input range up to ±12 V without an external bipolar supply, simplifying high-voltage industrial signal conditioning.
What package and pin count does the ADS8556IPMR use?
The ADS8556IPMR is supplied in a 64-pin thermally-enhanced HTQFP (S-PQFP-G64) plastic package with a heat slug for improved power dissipation. The footprint is suited to industrial drive and instrumentation boards that require compact multichannel acquisition.
Is the ADS8556IPMR RoHS-compliant and lead-free?
Yes. The ADS8556IPMR is fully RoHS-compliant and Pb-free with the e4 lead-finish code documented in the latest TI quality datasheet. Each unit ships with documented compliance for restricted hazardous substances suitable for global EU, US, and Asia-Pacific designs.
