Frequently Asked Questions
What resolution and input voltage range does the AD7899ARS-1 provide for industrial signal digitization?
The AD7899ARS-1 delivers 14-bit resolution with a ±10 V bipolar analog input range, allowing it to digitize both positive and negative industrial sensor signals with approximately 1.2 mV per LSB resolution. This combination of wide input span and 14-bit precision suits process control transmitters, strain gauge amplifiers, and thermocouple signal chains requiring accurate full-scale representation.
How fast does the AD7899ARS-1 complete an analog-to-digital conversion, and what throughput does that enable?
The AD7899ARS-1 achieves a maximum conversion time of 2.2 µs per sample, which supports throughput rates exceeding 450 kSPS when interface overhead is minimized. This speed makes it suitable for multiplexed data acquisition systems scanning 8 or 16 channels in rotating machinery monitoring, vibration analysis, and high-speed PLC analog input cards where fast settling is required between channel switches.
Is the AD7899ARS-1 suitable as a lead-free (RoHS) part for new designs, or is it restricted to legacy applications?
The AD7899ARS-1 carries JESD-609 code e0, indicating a tin-lead (SnPb) solder termination finish rather than a Pb-free finish. Its YTEOL rating of 0 suggests end-of-life supply status, so new designs requiring RoHS compliance and long-term supply should evaluate the AD7892 or AD7890 series successors. Existing legacy PCB assemblies using SnPb reflow processes can continue sourcing the 28-SSOP (RS-28) package from available inventory.
