TS7003ITD833

Analog To Digital Converters (ADC) Overview

The TS7003ITD833 is a single-supply, single-channel, 12-bit successive-approximation analog-to-digital converter (ADC) manufactured by Silicon Labs. It operates from a +2.7V to +3.6V supply and features a 300ksps sampling rate with a low conversion-mode supply current of 0.95mA. The device integrates a 10-MHz track-and-hold circuit and an internal ±0.6%, 30ppm/ºC +2.5V reference. It utilizes a 3-wire SPI/QSPI/Microwire serial interface and is housed in an 8-pin, 3mm x 3mm TDFN-EP package. The component is specified for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation. The datasheet lists TS7003ITD833T as the tape and reel variant with a quantity of 3000. Confirm that the received component matches the required packaging format and revision level before integration into production designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring a pin-compatible, higher-speed upgrade to the MAX1286. Ensure the system power supply remains within the +2.7V to +3.6V range. For optimal performance, maintain source impedance at 1kΩ or less or add an external input capacitor if higher impedance sources are used.

Analog To Digital Converters (ADC) Part Context

The TS7003 series includes variants such as the TS7003ITD833T. The ITD833 designation corresponds to the industrial temperature range (-40°C to +85°C) and the specific TDFN-EP package configuration. This part serves as a direct replacement for legacy ADCs in space-constrained, low-power data acquisition environments.

Analog To Digital Converters (ADC) Replacement Considerations

The TS7003 is documented as a pin-compatible, higher-speed upgrade to the Maxim Integrated MAX1286. Designers replacing the MAX1286 should verify that the increased sampling rate and voltage range compatibility meet their specific system requirements.
