LTC1605-2

LTC1605-1/LTC1605-2 Single Supply 16-Bit, 100ksps, Sampling ADCs FEATURES s s s s s s s s s DESCRIPTIO Sample Rate: 100ksps Complete 16-Bit Solution on a Single 5V Supply Unipolar Input Range: 0V to 4V (LTC1605-1) Bipolar Input Range: ±4V (LTC1605-2) Power Dissipation: 55mW Typ Signal-to-Noise Ratio: 86dB Typ Operates with Internal or External Reference Internal Synchronized Clock 28-Pin 0.3" PDIP and SSOP Packages The LTC ®1605-1/LTC1605-2 are 100ksps, sampling 16-bit A/D converters that draw only 55mW (typical) from a single 5V supply. These easy-to-use devices include a sample-and-hold, precision reference, switched capacitor successive approximation A/D and trimmed internal clock. The LTC1605-1’s input range is 0V to 4V while the LTC1605-2’s input range is ±4V. An external reference can be used if greater accuracy over temperature is needed. The ADC has a microprocessor compatible, 16-bit or two byte parallel output port. A convert 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.
