Freie-PM.de: 18-Bit, 1.6Msps, Pseudo-Differential Serial SAR ADC Achieves 96.5dB SNR Performance & Low 18mW Power

MILPITAS, CA – November 7, 2011 – Linear Technology Corporation introduces the LTC2369-18, a serial 18-bit, 1.6Msps pseudo-differential SAR analog-to-digital converter (ADC), which achieves impressive 96.5dB SNR and -120dB THD while supporting a 0V to 5V unipolar input range. The pseudo-differential input simplifies the ADC driver requirement, enabling single-ended drive while benefiting from the reduction of unwanted signals common to both inputs. This reduces complexity and lowers the power requirements in the signal chain. Operating from a 2.5V supply, the LTC2369-18 consumes only 18mW, with a low power shutdown mode that consumes just 2.25µW. When used in combination with the recommended single-ended ADC driver LT6202, the combined power dissipation is a mere 53mW, a 40% reduction from a fully differential drive circuit. The LTC2369-18 is the industry’s highest performing 18-bit pseudo-differential SAR ADC, featuring a maximum INL of ±2.5LSB with no missing codes and guaranteed specifications over the -40ºC to 125ºC temperature range.
Complementing the LTC2369-18 is the pin- and software-compatible 16-bit, 2Msps LTC2370-16. The LTC2370-16 achieves outstanding 94dB SNR and ±0.85LSB maximum INL. The LTC2369-18 and LTC2370-16 are the first in a family of 18-/16-bit high performance pseudo-differential SAR ADCs with speeds ranging from 250ksps to 2Msps. They offer a
user-friendly SPI interface, explicit Busy and Chain pins, I/O voltages from 1.8V to 5V and an internal oscillator that simplifies digital timing and minimizes external component count. Their true no-latency operation enables accurate one-shot measurements even after lengthy idle periods with no minimum sample rate required.
The LTC2369-18 family of 18-/16-bit pseudo-differential SAR ADCs broadens the LTC2379-18 family of up to 102dB SNR, fully differential SAR ADCs introduced earlier this year. Linear’s complete portfolio of high performance pseudo and fully differential 18-/16-bit SAR ADCs with high SNR, fast throughput and low power dissipation is ideal for high performance medical, industrial and automotive applications. The LTC2369-18 and LTC2370-16 are available in small 16-lead MSOP and 4mm x 3mm DFN packages. To achieve uncompromised AC performance, we recommend the low noise, low power LT6202 ADC driver. We also recommend the LTC6655, a precision external reference with high accuracy of ±0.025% max, 2ppm/ºC drift and low 0.25ppmP-P noise ideal for high precision applications. The DC1813A, an integrated demo board featuring the LT6202 ADC driver and LTC6655 reference, is available at www.linear.com or via a local Linear Technology sales office.
