Product details
Overview
ADC101S101CIMF from Texas Instruments is a single-channel, 10-bit successive-approximation analog-to-digital converter with SPI/QSPI/MICROWIRE/DSP-compatible serial interface, operating at 500 ksps to 1 Msps sample rates, consuming 2.0 mW at 3V and supporting 2.7V–5.25V supply voltage - used in portable instrumentation for high-resolution sensor digitization.
For engineers reviewing the ADC101S101CIMF datasheet, ADC101S101CIMF pinout, ADC101S101CIMF application, or ADC101S101CIMF equivalent, key selection considerations include guaranteed DNL (±0.7 LSB max), INL (±0.7 LSB max), SNR (61.2 dB min), full-power bandwidth (8–11 MHz), and industrial temperature range (−40°C to +85°C) across its specified sample rate range.
Technical Context
The ADC101S101CIMF employs a charge-redistribution DAC core with internal track-and-hold, enabling precise sampling over its full 500 ksps–1 Msps range without performance degradation. Its straight-binary output format and tri-state SDATA pin support seamless integration with microcontrollers and DSPs using standard 3-wire serial protocols.
Conversion is initiated on the falling edge of CS, with acquisition time (tACQ ≤ 350 ns) referenced to the 13th rising SCLK edge, and aperture jitter limited to 30 ps - ensuring stable timing behavior for dynamic signal capture in embedded control loops and remote data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit with no missing codes - guarantees monotonicity and deterministic code transitions across full input range. |
| Sample Rate Range | 500 ksps to 1 Msps - fully specified performance across entire range, eliminating need for derating at lower speeds. |
| INL / DNL | ±0.7 LSB max / ±0.7 LSB max - ensures accurate linearity for precision measurement applications like sensor conditioning. |
| SNR | 61.2 dB min at 100 kHz input - supports >9.8 ENOB for high-fidelity analog signal digitization. |
| Power Consumption | 2.0 mW at 3V / 10 mW at 5V in normal mode; 2.5 µW at 5V in shutdown - enables battery-powered operation with rapid wake-up. |
| Supply Voltage | 2.7V to 5.25V - allows direct interfacing with common logic rails and LDO outputs without level-shifting. |
| Operating Temperature | −40°C to +85°C - qualified for industrial and extended-temperature embedded environments. |
Pinout & Package
ADC101S101CIMF is packaged in a 6-lead WSON (NGF) or SOT-23 (DBV) package - both RoHS-compliant, thermally efficient, and suitable for space-constrained PCB layouts. The WSON variant features an exposed thermal pad recommended for grounding to improve thermal performance and noise immunity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Analog input | Single-ended input referenced to VA; accepts 0V to VA range - requires low-impedance source or anti-aliasing filter for AC signals. |
| VA | Analog supply | +2.7V to +5.25V power rail; also serves as reference - must be bypassed with 1 µF + 0.1 µF capacitors within 1 cm. |
| GND | Ground return | Common reference for analog and digital sections - critical for minimizing noise coupling between domains. |
| CS | Chip select | Falling-edge-triggered conversion start; high state places device in shutdown mode - enables burst-mode power management. |
| SDATA | Serial data output | Tri-state, MSB-first, straight-binary output with 3 leading zeros + 10 data bits + 2 trailing zeros - compatible with standard SPI frame formats. |
| SCLK | Serial clock input | Controls conversion timing and data readout; supports 25 kHz–20 MHz - determines maximum throughput and interface flexibility. |
Key Features
| Feature | Design Value |
|---|---|
| Full-range sample rate specification | Guaranteed DNL, INL, SNR, and THD across 500 ksps–1 Msps - eliminates design uncertainty when scaling throughput. |
| Low-power shutdown mode | 2.5 µW quiescent power at 5V - enables microamp-level system sleep current in portable and remote sensing nodes. |
| Flexible digital interface | SPI/QSPI/MICROWIRE/DSP compatibility with tri-state SDATA - simplifies host processor selection and firmware reuse. |
| Single-supply operation | 2.7V–5.25V VA rail powers analog and digital sections - reduces BOM count and layout complexity versus dual-supply ADCs. |
| Industrial temperature qualification | −40°C to +85°C operation with tested limits - supports deployment in uncontrolled environments without thermal derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADC101S051CIMF | Specified for 200–500 ksps range; identical pinout and interface but lower max sample rate. | Better suited for medium-speed applications where 1 Msps is unnecessary and lower power at reduced throughput is preferred. | Select when system sampling requirement is ≤500 ksps and cost optimization is prioritized over peak speed headroom. |
| ADC121S101CIMF | 12-bit resolution, same 500 ksps–1 Msps range, identical package and pinout - pin- and function-compatible per TI documentation. | Provides higher resolution for applications requiring <1 LSB error in wide-dynamic-range measurements (e.g., precision weigh scales). | Choose when additional 2 bits of resolution justify higher cost and slightly increased power (12.5 mW @ 5V vs. 10 mW). |

FAQ
What is the maximum guaranteed sample rate for ADC101S101CIMF?
The ADC101S101CIMF is fully specified up to 1 Msps across its operating temperature range and supply voltage (2.7V–5.25V). This maximum rate is ensured with tACQ ≤ 350 ns, fSCLK = 20 MHz, and proper timing margins - no derating required for industrial use cases.
Does ADC101S101CIMF require an external reference voltage?
No. The ADC101S101CIMF uses its VA supply pin as the reference - eliminating need for external precision references. Input range is 0V to VA, and all specifications (INL, DNL, SNR) are guaranteed with this internal ratiometric reference configuration.
Can ADC101S101CIMF interface directly with 1.8V logic microcontrollers?
Yes - digital inputs (CS, SCLK) tolerate voltages up to +5.25V regardless of VA, allowing safe interfacing with 1.8V, 3.3V, or 5V hosts. However, SDATA output swing is VA-referenced, so level-shifting may be needed if VA > host logic high threshold.
What is the quiet time (tQUIET) requirement between conversions for ADC101S101CIMF?
The ADC101S101CIMF requires a minimum tQUIET of 50 ns after SDATA enters tri-state (at 16th SCLK falling edge or CS rising edge) before initiating the next conversion. This ensures bus relinquish and prevents metastability during reacquisition.
Is ADC101S101CIMF pin-compatible with other devices in the ADC101Sxx1 family?
Yes - ADC101S101CIMF shares identical 6-pin SOT-23 (DBV) and WSON (NGF) footprints and pin functions with ADC101S021CIMF, ADC101S051CIMF, and ADC121S101CIMF. TI explicitly confirms full pin and function compatibility across this family for drop-in resolution or speed upgrades.
