LTC1608AIG#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1608AIG#TRPBF is a high-speed, 16-bit sampling analog-to-digital converter (ADC) operating at 500ksps. It features a differential input sample-and-hold with a –2.5V full-scale range and draws 270mW from ±5V supplies. The device includes an internal precision reference and offers two digitally selectable power shutdown modes: Nap (7mW) and Sleep (10mW). Key performance metrics include 90dB S/(N+D), –100dB THD, and 94dB SFDR. It utilizes a 36-lead SSOP package and provides a microprocessor-compatible 16-bit parallel output interface without pipeline delay.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging. Confirm the 'I' grade designation for the –40°C to +85°C industrial temperature range. Ensure the specific lot date code meets project requirements as manufacturing schedules may vary.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power consumption alongside high dynamic range. The internal reference simplifies design but requires bypassing REFCOMP with a 22µF capacitor. For systems needing extended temperature ranges beyond +85°C, verify availability of other grade variants.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1608 family of 16-bit ADCs. It is pin-compatible with the LTC1604 and shares similar control logic interfaces. The AIG variant specifically denotes the industrial temperature range and SSOP package configuration within the product line.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1604 is a pin-compatible alternative within the same family. Verify functional equivalence regarding shutdown modes and reference configurations before substitution.

Analog To Digital Converters (ADC) FAQ

How does the SHDN pin control power modes?

Driving SHDN low while CS is low selects Nap mode. Driving SHDN low while CS is high selects Sleep mode.

What is the wake-up time from Sleep mode?

Wake-up time depends on the REFCOMP capacitor value; it is approximately 80ms with the recommended 22µF capacitor.

Can the LTC1608 interface with 3V digital systems?

Yes, digital inputs recognize 3V or 5V levels, and the dedicated OVDD pin allows output swings compatible with 3V systems.
