24-bit 2 Msps ADC offers 145 dB dynamic range
This suits the LTC2380-24 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. It allows results to be read out with a serial clock as low as 2 MHz, 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 ±3.5 ppm while dissipating 28 mW from a single 2.5V supply.
The LTC2380-24 is available in MSOP-16 and 4 × 3 mm DFN-16 packages, priced starting at $31.95 (1,000). It is drop-in compatible with the LTC2378-20 family of 1 Msps 0.5 ppm INL no-latency SAR ADCs, allowing system upgrades to 24 bits.
