LTC offer high precision 32-bit SAR ADC

Many high performance applications, including data acquisition, industrial control and medical instrumentation, require both accuracy and speed. This is often achieved by using a high resolution delta-sigma ADC and a high speed SAR ADC in the same system.

The LTC2508-32 simplifies such hybrid ADC system design by simultaneously providing both a 32-bit low noise digitally filtered output and a 14-bit 1Msps no latency output.

Since these outputs are generated from a single 32-bit SAR ADC core, the high accuracy and high speed outputs are perfectly matched, even as the operating temperature, supply and stress vary. In contrast to traditional solutions employing two distinct unmatched ADCs, the unique combination of both accuracy and speed in the LTC2508-32 enables much higher system performance while reducing solution size and lowering component count.

The LTC2508-32 is ideal for applications that simultaneously require precision measurement and fast tracking of signals. The exceptional 3.5ppm guaranteed maximum linearity, together with up to 145dB of dynamic range, enables the LTC2508-32 to make precision measurements in the presence of noise.
