4V (LTC1605-2)
sample-and-hold, precision reference, switched capacitor n
Power Dissipation: 55mW Typ
successive approximation A/D and trimmed internal clock. n Signal-to-Noise Ratio: 86dB Typ The LTC1605-1’s input range is 0V to 4V while the n Operates with Internal or External Reference LTC1605-2’s input range is ±4V. An external reference n Internal Synchronized Clock can be used if greater accuracy over temperature is n 28-Pin SSOP Package needed. The ADC has a microprocessor compatible, 16-bit or two
