The LTC2229CUH#PBF is an Analog to Digital Converter (ADC) belonging to the field of data acquisition. It is an ultra high speed dual 12-bit sampling ADC that can sample up to 1GSPS with up to 105dB SNR and -94dBFS INL. It has two independent, parallel-delivered data channels which makes this ADC very suitable for dynamic signal application requirements, such as radar, SatCom, and communications.

The LTC2229CUH#PBF implements a successive approximation register architecture, which is a digital-to-analog converter and buffer amplifier (used to convert digital codes into analog signals) integrated in one analog to digital converter. The LTC2229CUH#PBF is programmed using the serial peripheral interface (SPI), which allows the user to configure the ADC to particular settings. The SPI is also used to read the results of the ADC conversion. There are two user programmable digital filter types that can be used to reduce noise or interference, which makes it flexible to use in a variety of applications.

The LTC2229CUH#PBF also has hot spare (HS) operation and simultaneous sampling feature. Humming bird mode can offer programmable data rates from DC to 1500 kHz allowing the device to transition smoothly between different clock speeds. Multiple outputs can be used with HS operation, allowing the LTC2229CUH#PBF to sample and shut down each output while still holding the results of the previous conversion. Additionally, the LTC2229CUH#PBF utilizes a patented low latency simultaneous sampling feature that results in much faster operation when the application requires both channels to operate at higher clock speeds.

The LTC2229CUH#PBF uses a high performance differential FET sample-and-hold front-end to reduce settling times and EMI. The device also supports a low power mode and has adjustable power saving features that can further reduce power consumption. Additionally, the LTC2229CUH#PBF includes adjustable analog gain and offset trim to reduce gain errors, drift, and leakage errors.

In conclusion, the LTC2229CUH#PBF is an excellent ADC for applications needing high speed dual 12-bit sampling at 1GSPS. It has a number of features that make it flexible and suitable for a variety of dynamic signal applications. It also has adjustable power saving features and adjustable gain and offset trim to optimize performance. Finally, it can support programmable data rates, as well as hot spare and simultaneous sampling, making it a great choice for applications requiring high speed data acquisition.
