LTC2295IUP

Analog To Digital Converters (ADC) Overview

The LTC2295IUP is a dual-channel, 14-bit analog-to-digital converter (ADC) operating at a sampling rate of 10Msps. Designed for low-power applications with a single 3V supply (2.7V to 3.4V), it consumes approximately 120mW. The device features a flexible input range of 1VP-P to 2VP-P and includes an internal reference. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 74.4dB and Spurious-Free Dynamic Range (SFDR) of 90dB. It utilizes a pipelined architecture with a pipeline latency of five cycles and offers multiplexed or separate digital output buses.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix when purchasing. The base model number is LTC2295. Add #TR for tape and reel packaging, #PBF for lead-free compliance, or #TRPBF for lead-free tape and reel. Confirm the temperature grade; the 'I' suffix indicates an industrial operating range of -40°C to 85°C, while 'C' denotes commercial range. Ensure the package type matches the required footprint.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2295IUP for applications requiring dual channels with 14-bit resolution at 10Msps. Choose this part over higher-speed variants like the LTC2299 (14-bit, 105Msps) if lower power consumption is prioritized. Ensure the system supports the required 3V analog supply and appropriate OVDD levels for the digital interface. Verify that the input signal amplitude fits within the selectable ±0.5V or ±1V ranges via the SENSE pins.

Analog To Digital Converters (ADC) Part Context

The LTC2295 belongs to a pin-compatible family of dual ADCs from Analog Devices. This family includes models with varying speeds and resolutions, such as the LTC2290 (12-bit, 10Msps) and LTC2299 (14-bit, 105Msps). The LTC2295 specifically targets the 10Msps segment with 14-bit resolution, offering a balance between performance and power efficiency compared to faster counterparts in the series.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the LTC2299 (14-bit, 105Msps) for higher speed requirements or the LTC2290 (12-bit, 10Msps) for cost-sensitive applications with lower resolution needs. Ensure voltage levels and power budgets align with the selected substitute.
