TS7003ITD833 - 12-Bit 300ksps SAR ADC, 2.5V Ref, TDFN-8 | Silicon Labs
The Silicon Labs TS7003ITD833 is a 12-bit, 300 ksps successive-approximation analog-to-digital converter (ADC) with a single-ended single-channel input, integrated +2.5V reference, and a high-speed serial digital interface, packaged in an 8-pin TDFN (3x3 mm) with exposed pad for thermal and ground integrity. Designed for single-supply operation from +2.7V to +3.6V, it draws less than 1 mA at full 300 ksps conversion rate.
An ADC in this product category is a mixed-signal data converter that translates real-world analog voltages into discrete digital codes. The successive-approximation register (SAR) architecture family uses a binary-search algorithm with an internal track-and-hold front end, achieving a balance of speed, accuracy, and low power consumption suitable for embedded sensing, instrumentation, and process-control front-ends. This part sits within the broader hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor. Its integrated reference removes an external component and reduces board area, an important benefit for compact sensor-interface designs.
Key features include 12-bit resolution, 300 ksps throughput, a high-bandwidth input track-and-hold amplifier, and an internal +2.5V reference. The serial interface reduces pin count compared to parallel-output ADCs, simplifying routing and host-MCU connection. Low conversion-mode power consumption and an industrial temperature range support battery-aware and factory-floor deployments alike.
The TS7003ITD833 successive-approximation architecture implements a charge-redistribution DAC internally, capturing input samples on the T/H at the rising edge of CNVST and presenting results one frame later through the SPI-compatible serial port. The integrated reference and single-supply rail minimizes external component count, while the 8-pin TDFN EP package provides a low-impedance thermal/ground path that enhances noise immunity at full throughput.
Typical applications include industrial process-control analog front-ends, portable battery-powered data loggers, sensor-signal digitizers, weigh-scale and load-cell readouts, and microcontroller-based instrumentation. Use it where channel count is small, sampling rate is moderate, and PCB real estate is at a premium.
When designing with this ADC, place the decoupling capacitor directly between AVDD and GND, keep analog and digital ground returns separated until they join at the exposed pad, and respect the tACQ acquisition-time timing parameter when writing firmware. Driving the analog input from a low-impedance buffer maintains data-sheet linearity at high source resistances.
This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet to help procurement and design engineers evaluate the TS7003ITD833 for new designs and second-source risk mitigation.
