Product details

What this ADC brings to the signal chain

The LTC2247IUH#PBF is a 14-bit pipelined ADC from Analog Devices that samples at 40 MSps. It accepts both differential and single-ended inputs through a single channel, with an internal S/H stage ahead of the converter core. The parallel data interface keeps latency low — useful for imaging, radar, or communications receivers where sample-to-output delay matters. The pipelined architecture delivers 14-bit resolution at 40 MSps without the power penalty of a flash converter, making it a fit for mid-speed instrumentation and IF-sampling chains.

Supply rails and reference flexibility

The reference can be driven externally or generated internally.

The industrial range covers most applications that aren't full military or downhole — if your system lives inside a conditioned lab or office, the commercial-grade sibling (if one exists) would also work, but the IUH suffix already carries the wider range.

Frequently asked questions

What is the resolution of LTC2247IUH#PBF?

14 bits. Combined with the 40 MSps sampling rate, this gives a theoretical SNR of about 86 dB for a full-scale sine wave.

Does LTC2247IUH#PBF require an external reference?

No — it accepts either an external or internal reference. The internal reference is sufficient for most designs, but an external precision reference can be used when tighter accuracy is needed.
