LTC1279 12-Bit, 600ksps Sampling A/D Converter with Shutdown Features s s s s s s s s s s DESCRIPTIO s Single Supply 5V or ± 5V Operation Sample Rate: 600ksps 70d B S/(N + D) and 74d B THD at Nyquist Power Dissipation: 60m W Typ Power Shutdown with Instant Wake-Up Internal Reference Can Be Overdriven Externally Internal Synchronized Clock; No Clock Required High Impedance Analog Input Input Range: 0V to 5V or ± 2.5V New Flexible, Friendly Parallel Interface Eases Connections to DSPs and FIFOs 24-Pin SO Wide Package The LTC®1279 is a 1.4µs, 600ksps, sampling 12-bit A/D converter which draws only 60m W from a single 5V or ± 5V supplies. This easy-to-use device es plete with a 160ns sample-and-hold, a precision reference and an internally trimmed clock. Unipolar and bipolar conversion modes add to the flexibility of the ADC. The low power dissipation is reduced even more, drawing only 8.5m W in power shutdown mode. Instant wake-up from power shutdown allows the converter to be powered down even during brief inactive periods. The LTC1279 converts 0V to 5V unipolar inputs from a single 5V supply and ± 2.5V bipolar inputs from ± 5V supplies. Maximum DC specs include ± 1LSB INL and ± 1LSB DNL. Outstanding guaranteed AC performance includes 70d B S/(N + D) and 78d B THD at the input frequency of 100k Hz over temperature. The internal clock is trimmed for 1.4µs conversion time. The clock automatically synchronizes to each sample mand, eliminating problems with asynchronous clock noise found in petitive devices. A separate conversion start input and a data-ready signal (BUSY) ease connections to FIFOs, DSPs and microprocessors. , LTC and LT are registered trademarks of Linear Technology Corporation.
