16-bit, 1-Msps, low power SAR ADC features digital timing interface
September 16, 2010 // Paul Buckley
Linear Technology Corporation has introduced an easy-to-use, low power 16-bit 1-Msps serial SAR ADC with guaranteed specifications over the -40 to 125 degrees C temperature range. Consuming 13 mW from a single 2.5 V supply, the LTC2383-16 achieves an 92 dB SNR and -106 dB THD from a fully differential +2.5 V input range while maintaining a maximum +2LSB INL and no missing codes.
Available in 3 mm x 4 mm DFN and MSOP-16 packages, the LTC2383-16 is ideal for space-constrained applications that require low power, including those using multiple ADCs per board.
Complementing the LTC2383-16 are the pin- and software-compatible LTC2382-16 (500 ksps) andLTC2381-16 (250 ksps). These devices feature a proprietary sampling architecture that allows the ADCs to begin acquiring the next sample during the current conversion. This extends the acquisition time and allows the use of low power ADC drivers, further reducing the overall power budget.
The user friendly ADCs feature a simple digital timing interface and require few external components. All feature a shutdown mode that reduces power dissipation to 1.25 uW when not converting. True no latency operation enables accurate one-shot measurements even after lengthy idle periods with no minimum sample rate required. The flexible serial SPI interface supports I/O voltages from 1.8 V to 5 V. To support robust customer designs with long product lifetimes, all key AC and DC specs including THD and sleep current are guaranteed.
Availability and Pricing
The DC1571A, an integrated demo board featuring the LTC6652-2.5 reference and LT6350 driving the LTC2383-16 ADC, is available now. All devices are available now in production quantities, priced starting at 12.20 US Dollars for the LTC2383-16, 8.50 US Dollars for the LTC2382-16 and 7.20 US Dollars for the LTC2381-16 in 1,000-piece quantities.
