Linear Technology has introduced the LTC2369-18, a serial 18-bit, 1,6 MSps pseudo-differential SAR analog-to-digital converter (ADC), which achieves 96,5 dB SNR and -120 dB THD while supporting a 0 V to 5 V 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 2,5 V supply, the IC consumes only 18 mW, with a low-power shutdown mode that consumes just 2,25 μW.
When used in combination with the recommended single-ended ADC driver LT6202, the combined power dissipation is a mere 53 mW, a 40% reduction from a fully differential drive circuit. The LTC2369-18 features a maximum INL of ±2,5 LSB with no missing codes and guaranteed specifications over the -40°C to 125°C temperature range.
Complementing the LTC2369-18 is the pin- and software-compatible 16-bit, 2 MSps LTC2370-16 which achieves 94 dB SNR and ±0,85 LSB maximum INL. The devices are the first in a family of 18-/16-bit pseudo-differential SAR ADCs with speeds ranging from 250 KSps to 2 MSps. They offer a user-friendly SPI interface, explicit Busy and Chain pins, I/O voltages from 1,8 V to 5 V and an internal oscillator that simplifies digital timing and minimises external component count. Their true no-latency operation enables accurate one-shot measurements even after lengthy idle periods with no minimum sample rate required.
