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.

Linear introduces lowest noise, 16-Bit 20 Msps ADCs that achieve 84 dB SNR

Linear Technology Corp. introduces three low power 16-bit, 20Msps analog-to-digital converters (ADCs), the LTC2269, LTC2270 and LTC2271, offering the lowest input-referred noise and tight integral nonlinearity error (INL) for very high precision DC measurements. With only 46µVRMS input noise and maximum guaranteed INL error of ±2.3LSB, these ADCs are suitable for very low noise, high linearity sampling applications such as digital x-ray, infrared and medical imaging, pachymeters, spectrometry and cytometry.

Linear introduces low noise fully differential 1.6GHz buffer

Linear Technology announces the LTC6417, a fully differential buffer amplifier with only 1.5nV/√Hz output-referred noise. The LTC6417 is capable of driving a differential 50 Ohm load and is optimized for driving 14- and 16-bit pipeline ADCs. It can be DC- or AC-coupled at its inputs, and achieves excellent distortion performance for signals up to and beyond 600 MHz. At 140 MHz, OIP3 is 46 dBm, and HD3 is -69 dBc with 2.4 VP-P output swing into a 50Ohm load.
