Linear introduces 18 Bit, 1 Msps, ±10.24 V true bipolar SAR ADC

Linear Technology Corp. introduces the LTC2338-18, an 18-bit 1 Msps no latency 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 5V supply, achieves 100 dB SNR and -110 dB THD 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.
