24­Bit 2Msps SAR ADC Achieves 145dB Dynamic Range
MILPITAS, CA – November 3, 2015 – Linear Technology Corporation introduces the LTC238024, a breakthrough no latency 24-bit 2Msps successive approximation register (SAR) analog-todigital 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 LTC238024 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 × 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
