LTC1606 16-Bit, 250ksps, Single Supply ADC FEATURES DESCRIPTIO Sample Rate: 250ksps The LTC 1606 is a 250ksps, sampling 16-bit A/D con- Single 5V Supply verter that draws only 75mW (typical) from a single 5V Bipolar Input Range: 10V supply. This easy-to-use device includes sample-and- Signal-to-Noise Ratio: 90dB Typ hold, precision reference, switched capacitor successive Power Dissipation: 75mW Typ approximation A/D and trimmed internal clock. Guaranteed No Missing Codes The LTC1606s input range is an industry standard 10V. Integral Nonlinearity: 2.0LSB Max Maximum DC specs include 2.0LSB INL and 16 bits no Operates with Internal or External Reference missing codes over temperature. An external reference Internal Synchronized Clock can be used if greater accuracy over temperature is 28-Pin SSOP and SO Packages needed. 100ksps Version (LTC1605) The 90dB signal-to-noise ratio offers an improvement of Improved 2nd Source to AD976A and ADS7805 3dB over competing devices, and the RMS transition noise Available in 28-Lead Plastic SSOP and SO Packages U is reduced (0.65LSB vs 1LSB) relative to competitive APPLICATIO S parts. The ADC has a microprocessor compatible, 16-bit or two Industrial Process Control byte parallel output port. A convert start input and a data Multiplexed Data Acquisition Systems High Speed Data Acquisition for PCs ready signal (BUSY) ease connections to FIFOs, DSPs and microprocessors.
