Product details
Overview
ADCS7476AIMFE/NOPB from Texas Instruments is a 12-bit, 1-MSPS successive-approximation analog-to-digital converter (SAR ADC) with internal track-and-hold, single-supply operation (2.7 V to 5.25 V), SPI-compatible serial interface, and supply-as-reference architecture enabling 0–VDD input range. It delivers ±0.4 LSB typical INL, 72 dB SINAD at 100 kHz, and 2 mW power consumption at 3 V - deployed in automotive navigation and portable instrumentation.
For engineers reviewing the ADCS7476AIMFE/NOPB datasheet, ADCS7476AIMFE/NOPB pinout, ADCS7476AIMFE/NOPB application, or ADCS7476AIMFE/NOPB equivalent, key selection criteria include guaranteed no-missing-codes 12-bit resolution over −40°C to 125°C, 20 MHz SCLK support, shutdown mode consuming <5 µW, and 6-pin SOT-23 footprint for space-constrained embedded sensing.
Technical Context
The ADCS7476AIMFE/NOPB implements a charge-redistribution SAR architecture with integrated track-and-hold, where sampling occurs on the falling edge of CS and conversion completes within 16 SCLK cycles. Its straight binary output format yields an LSB step of VDD/4096, and full-scale range scales directly with supply voltage.
Serial communication uses a 3-wire SPI-compatible interface (CS, SCLK, SDATA) with timing-defined data framing: four leading zeros followed by twelve data bits, no trailing zeros. The device supports variable throughput via SCLK frequency (up to 20 MHz) and enters ultra-low-power shutdown (<5 µW at 5 V) when CS remains high and SCLK inactive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - guarantees monotonicity and full code coverage across −40°C to 125°C operating range. |
| Sampling Rate | 1 MSPS maximum - enables real-time digitization of signals up to ~400 kHz (Nyquist-limited) in continuous mode. |
| INL | ±0.4 LSB typical at 25°C - ensures high DC accuracy for precision sensor interfacing and calibration-critical systems. |
| SINAD | 72 dB at 100 kHz input - supports >11.5 effective number of bits (ENOB) for medium-bandwidth signal acquisition. |
| Power Consumption | 2 mW at 3 V / 1 MSPS - enables battery-powered operation with minimal thermal impact in portable medical or industrial devices. |
| Supply Range | 2.7 V to 5.25 V - allows direct integration with common logic rails without external regulators or references. |
| Input Range | 0 V to VDD - eliminates need for external level-shifting or reference buffers in single-supply systems. |
Pinout & Package
ADCS7476AIMFE/NOPB is housed in a 6-pin SOT-23 package (1.60 mm × 2.90 mm body size), optimized for high-density PCB layouts in automotive and portable applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive supply and reference input | Must be bypassed with 0.1 µF + 1 µF capacitors within 1 cm; sets full-scale analog input range (0 to VDD). |
| GND (Pin 2) | Analog/digital ground return | Common reference for analog input, digital I/O, and internal circuitry; requires low-impedance connection to system ground plane. |
| VIN (Pin 3) | Analog input | Accepts single-ended 0–VDD signals; 30 pF input capacitance requires careful driver impedance matching for settling. |
| SCLK (Pin 4) | Serial clock input | Controls conversion timing and data readout; supports 10 kHz–20 MHz frequencies with 40%–60% duty cycle. |
| SDATA (Pin 5) | Serial data output | Tri-state CMOS output delivering 16-bit frame (4 leading zeros + 12 data bits) on SCLK falling edges. |
| CS (Pin 6) | Chip select input | Falling edge initiates conversion and data transfer; rising edge or 16th SCLK falling edge returns SDATA to high-impedance state. |
Key Features
| Feature | Design Value |
|---|---|
| Supply-as-reference architecture | Eliminates external voltage reference component and associated layout complexity while maintaining full-scale tracking with VDD. |
| Ultra-low-power shutdown mode | Reduces current draw to 0.5 µA (5 V) or 0.3 µA (3 V), enabling microamp-level system sleep states without sacrificing wake-up latency. |
| SPI/QSPI/MICROWIRE/DSP compatibility | Ensures plug-and-play integration with diverse host controllers including C2000™, MSP430™, and ARM® Cortex-M microcontrollers. |
| Automotive-grade temperature range | Specified for −40°C to 125°C operation - qualified for under-hood and infotainment subsystems per AEC-Q100 stress requirements. |
| Small-footprint SOT-23 packaging | Enables placement adjacent to sensors or signal-conditioning circuitry with minimal board area (4.6 mm² footprint). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7476AARMZ | 12-bit, 1 MSPS, but uses external reference and requires dual supplies (AVDD/DVDD); higher DNL (±1 LSB max) and wider temp range (−40°C to 125°C same). | Requires external reference buffer and separate analog/digital supplies - increases layout complexity and BOM cost. | Select AD7476AARMZ only if external reference precision or legacy Analog Devices ecosystem compatibility is required. |
| ADS7822U | 12-bit, 200 kSPS max, supply-as-reference, but slower throughput and lower SINAD (69 dB); same 6-pin SOT-23 package. | Not suitable for 1-MSPS applications like motor control or wideband sensor sampling; better for low-throughput, ultra-low-power monitoring. | Choose ADS7822U when average power must stay below 1 mW and sampling rate ≤200 kSPS suffices. |
Compared with AD7476AARMZ and ADS7822U, ADCS7476AIMFE/NOPB uniquely combines 1-MSPS throughput, supply-as-reference simplicity, and automotive-grade reliability in a 6-pin SOT-23 - making it optimal for space- and power-constrained real-time sensing where reference integration and timing determinism are critical.

FAQ
What is the maximum clock frequency supported by ADCS7476AIMFE/NOPB?
The ADCS7476AIMFE/NOPB supports a maximum SCLK frequency of 20 MHz across its full operating temperature range (−40°C to 125°C). At this rate, it achieves its rated 1-MSPS throughput with guaranteed timing margins per the datasheet's AC electrical characteristics table. Operation above 20 MHz is not characterized and may result in conversion errors or data corruption.
Does ADCS7476AIMFE/NOPB require an external voltage reference?
No, ADCS7476AIMFE/NOPB does not require an external voltage reference. It uses the VDD supply as its reference, establishing a full-scale input range of 0 V to VDD. This simplifies system design by eliminating external reference components, associated decoupling, and layout sensitivity - confirmed in the "Description" and "Electrical Characteristics" sections of the SNAS192G datasheet.
What is the power consumption of ADCS7476AIMFE/NOPB during active conversion at 3 V?
At 3 V supply and 1-MSPS operation, ADCS7476AIMFE/NOPB consumes 2 mW typical (0.6 mA current) at 25°C, rising to 4.8 mW (1.6 mA) at −40°C to 85°C. These values are specified in Section 6.5 "Electrical Characteristics – ADCS7476" of the SNAS192G datasheet and reflect operational power during continuous conversion with SCLK active.
How many bits does ADCS7476AIMFE/NOPB output per conversion, and what is the data format?
ADCS7476AIMFE/NOPB outputs a 16-bit serial frame: four leading zeros followed by twelve straight binary data bits (MSB first), with no trailing zeros. The complete word is clocked out on the falling edges of SCLK, beginning after the CS falling edge - as detailed in Section 7.3 "Feature Description" and Figure 2 of the SNAS192G datasheet.
Is ADCS7476AIMFE/NOPB qualified for automotive applications?
Yes, ADCS7476AIMFE/NOPB is explicitly designed and tested for automotive use, with a guaranteed operating temperature range of −40°C to 125°C and qualification per AEC-Q100 stress test requirements. Its applications list includes "Automotive Navigation," and the "Description" section confirms automotive and extended industrial temperature range suitability.
