The new LTC2338-18 from Linear Technology is an 18-bit, 1 MSps successive approximation register (SAR) analog-to-digital converter (ADC) with a wide ±10,24 V fully differential, true bipolar input range for high-voltage, industrial applications.
The device operates from a single 5 V supply, achieves 100 dB signal-to-noise ratio and -110 dB total harmonic distortion and features an internal 2,048 V (20 ppm/°C max) reference and reference buffer. An input divider network scales and level shifts the input signal, eliminating complicated circuitry required to directly interface true bipolar signals.
The IC leads a pin- and software-compatible family of 18-bit serial SPI SAR ADCs with speeds ranging from 250 KSps to 1 MSps. A pin-compatible 16-bit and 18-bit family with pseudo differential true bipolar inputs (LTC2328-18) will also be available.
The proprietary internal reference buffer maintains less than 1 LSB error during sudden bursts of conversions, enabling true one-shot operation after lengthy idle periods. These ADCs operate from a single 5 V supply and consume just 50 mW at 1 MSps. Power further reduces linearly at slower sample rates and a shutdown mode dissipates only 300 μW when idle.
The fully differential LTC2338-18 and pseudo differential LTC2328-18 families are available in small MSOP-16 packages in commercial, industrial and automotive temperature grades.
