Data acquisition applications often need to convert analog signals to digital information that can be used by the host microprocessor, which is the fundamental job of an analog-to-digital converter (ADC). The LTC1859CG#PBF is an 8-bit analog-to-digital converter with serial interface that has specially been designed to meet the needs of high data throughput applications. It is also ideal for applications requiring low power consumption.

The LTC1859CG#PBF is a high-performance 8-bit ADC that can handle data transfer rates up to 250 kSPS. It comes in the 24-lead SSOP package and requires a single-supply voltage between 3.2 and 5.5 volts for operation. It features an onboard voltage reference and is capable of converting unipolar, bipolar and differential single-ended signals to digital values. The ADC also features an 11-bit reference resistor network that eliminates the need for external resistors.

The onboard voltage reference provides a reference voltage of 2.5 V. This makes it suitable for applications where a higher reference voltage is needed. The ADC features an input analog range between 0 V and 2.5 V which makes it suitable for applications requiring single-ended bipolar input signals. The ADC also features a fast conversion cycle of 5.0 μs.

The LTC1859CG#PBF has a sample-and-hold amplifier that can hold the input signal for a maximum sample period of 1.5 μs. This makes it suitable for applications where the input signal needs to be sampled for a short period of time before the ADC begins its conversion cycle. The ADC also features an auto-zero function that reduces the input offset error within the ADC. This makes it suitable for high-accuracy data acquisition applications.

The LTC1859CG#PBF can be used in many applications, such as instrumentation and control, medical, communication and data acquisition. In instrumentation and control applications, it can be used to convert analog signals from transducers and sensors, such as pressure, temperature, and flow, into digital signals that can be processed and logged by a microprocessor. The ADC can also be used in medical applications, such as monitoring patient vital signs and patient health, where it can convert analog signals into digital signals and transmit them to a microprocessor.

The LTC1859CG#PBF can also be used in communication applications, such as in point-to-point and broadcast telemetry, where it can convert analog signals representing data from sensor networks and transmit them to a microprocessor. Finally, it can be used in data acquisition applications, such as in digital oscilloscopes, where it can convert analog signals from electronic test equipment into digital signals that can be displayed or stored on a computer for further analysis.

In conclusion, the LTC1859CG#PBF is a suitable and high-accuracy ADC for a variety of applications requiring high data throughput, low power consumption and lower reference voltage. It features an onboard voltage reference, auto-zero and sample-and-hold functions. It can be used in instrumentation and control, medical, communication and data acquisition applications.
