24-Bit 2Msps SAR ADC Achieves 145dB Dynamic Range

MILPITAS, CA - November 3, 2015 - Linear Technology Corporation introduces the LTC2380-24, a breakthrough no latency 24-bit 2Msps successive approximation register (SAR) analog-to-digital converter (ADC). The LTC2380-24 features an integrated digital filter that averages 1 to 65,536 conversion results real time, dramatically improving the dynamic range from 101dB at 1.5Msps to 145dB at an output data rate of 30.5sps. This makes the LTC2380-24 ideal for seismic, medical and many other applications demanding high dynamic range.

Using an on-chip digital filter to average conversion results, the LTC2380-24 eliminates the processing burden from the digital host, conserving digital resources and the associated power. Moreover, the LTC2380-24 allows results to be read out with a serial clock as low as 2MHz, easing interfacing to microprocessors, enabling use with slower devices. The LTC2380-24 achieves true 24-bit noise performance and features high DC accuracy with a maximum INL of ±3.5ppm while dissipating 28mW from a single 2.5V supply.

The LTC2380-24 is available in small MSOP-16 and 4mm x 3mm DFN-16 packages, priced starting at $31.95 each in 1,000 piece quantities. It is drop-in compatible with the LTC2378-20 family of 1Msps 0.5ppm INL no latency SAR ADCs, allowing easy system upgrades to 24 bits. Samples and demo boards may be requested at www.linear.com/product/LTC2380-24, or by contacting your local Linear Technology sales office.
