LTC1415 12-Bit, 1.25Msps, 55mW Sampling A/D Converter
The LTC®1415 is a 700ns, 1.25Msps, 12-bit sampling A/D converter that draws only 55mW from a single 5V supply. This easy-to-use device includes a high dynamic range sample-and-hold, precision reference and a trimmed internal clock. Two power shutdown modes provide flexibility for low power systems.
The LTC1415’s full-scale input range is 4.096V. Low linearity errors ±0.35LSB INL, ±0.25LSB DNL make it ideal for imaging systems. Outstanding AC performance includes 72dB S/(N + D) and 80dB THD with an input frequency of 100kHz.
The unique differential input sample-and-hold can acquire single-ended or differential input signals up to its 18MHz bandwidth. The 60dB common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source.
The ADC has a µP compatible, 12-bit parallel output port. There is no pipeline delay in the conversion results. A separate convert start input and data ready signal (BUSY) ease connections to FIFOs, DSPs and microprocessors. A separate output logic supply pin allows direct connection to 3V components
