High Precision, Multiplexed 24-bit ADC

( 1 Apr 2006 )

Linear Technology introduces the LTC2442, a multiplexed 24-bit No Latency Delta Sigma ADC with an integrated high performance amplifier. The LTC2442 achieves 1 ppm linearity with the amplifier configured as a unity gain buffer. This converter allows the amplifier supply rails to be connected to VCC and ground or biased beyond the rails for rail-to rail input signals. The LTC2442’s proprietary architecture rejects channel-to-channel crosstalk and is immune to lockup due to large input disturbances. This combination of high precision and high input impedance makes the part suitable for demanding industrial and scientific instrumentation applications.Linear Technology
