Product details
Overview
ADC124S051CIMM/NOPB from Texas Instruments is a 12-bit, 4-channel successive-approximation ADC with serial SPI-compatible interface, operating at 200–500 ksps sample rates, 72.5 dB typical SNR, ±0.5 LSB INL, and single-supply 2.7V–5.25V operation - used in portable instrumentation for multi-sensor analog signal digitization.
For engineers reviewing the ADC124S051CIMM/NOPB datasheet, ADC124S051CIMM/NOPB pinout, ADC124S051CIMM/NOPB application, or ADC124S051CIMM/NOPB equivalent, key selection criteria include guaranteed 12-bit no-missing-code performance across industrial temperature (−40°C to +85°C), low-power shutdown mode (0.14 µW @ 3V), and VSSOP-10 package compatibility with space-constrained embedded data acquisition systems.
Technical Context
The ADC124S051CIMM/NOPB implements a charge-redistribution SAR architecture with integrated track-and-hold, supporting four independent analog inputs (IN1–IN4) via internal multiplexer. Conversion timing is fully synchronous to SCLK, requiring 16 clock cycles per frame (3 for track, 13 for hold/convert/readout), with MSB-first straight-binary output on DOUT.
It uses VA as both supply and reference, eliminating external reference components but requiring tight supply decoupling (1 µF tantalum + 0.1 µF ceramic). Control register loading occurs on DIN during the first 8 rising SCLK edges after CS fall, enabling dynamic channel selection between conversions without reconfiguration overhead.
Key Specifications

Pinout & Package
ADC124S051CIMM/NOPB is housed in a 10-lead VSSOP (Package Code DGS), 3.0 mm × 3.0 mm × 0.9 mm body, with exposed thermal pad (not electrically connected). Pin spacing is 0.5 mm; recommended solder profile complies with TI's lead-free reflow specifications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - CS | Chip Select | Falling edge initiates conversion frame; high state enables power-down and tri-states DOUT. |
| 2 - VA | Analog Supply / Reference | Single 2.7–5.25 V supply; also serves as full-scale reference - requires local 1 µF + 0.1 µF bypassing. |
| 3 - GND | Analog Ground | Common return for analog signals and supply - must be star-connected to minimize noise coupling. |
| 4–7 - IN1 to IN4 | Analog Inputs | Four single-ended channels, each 0–VA range; input capacitance 33 pF (track) / 3 pF (hold). |
| 8 - DIN | Serial Data Input | Loads 8-bit control register (ADD2:ADD0) on rising SCLK edges to select next input channel. |
| 9 - DOUT | Serial Data Output | MSB-first 12-bit result clocked out on falling SCLK edges; tri-stated when CS is high. |
| 10 - SCLK | Serial Clock | Master clock (50 kHz–16 MHz); controls conversion timing, data transfer, and internal logic sequencing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADC124S021 | Same pinout and interface; lower max sample rate (50–200 ksps); reduced power (1.5 mW @ 3V) | Better suited for low-throughput sensor nodes where 200 ksps is sufficient | Select ADC124S021 when system sampling requirement is ≤200 ksps and lowest possible active power is critical. |
| ADC122S101 | Same pinout and interface; higher max sample rate (500 ksps–1 Msps); higher power (15 mW @ 5V) | Required for applications needing >500 ksps sustained throughput or tighter timing jitter | Choose ADC122S101 only if design requires guaranteed 1 Msps operation or improved aperture uncertainty at high speeds. |

FAQ
What is the absolute maximum supply voltage for ADC124S051CIMM/NOPB?
The absolute maximum supply voltage (VA) for ADC124S051CIMM/NOPB is 6.5 V, as specified in the Absolute Maximum Ratings table. Operation above +5.25 V - the maximum recommended supply - risks permanent damage even if within the 6.5 V limit. The device is characterized and guaranteed only from +2.7 V to +5.25 V, and all electrical specifications assume operation within this range. Exceeding +5.25 V voids performance guarantees and may degrade long-term reliability.
Does ADC124S051CIMM/NOPB require an external voltage reference?
No, ADC124S051CIMM/NOPB does not require an external voltage reference. It uses its analog supply voltage (VA) as the internal reference, resulting in a full-scale range of 0 V to VA. This simplifies design by eliminating external reference components and associated layout complexity. However, because VA serves dual roles, any noise or ripple on the supply directly impacts conversion accuracy - hence the datasheet mandates local bypassing with a 1 µF tantalum and 0.1 µF ceramic capacitor placed within 1 cm of the VA pin.
How many analog input channels does ADC124S051CIMM/NOPB support, and how are they selected?
ADC124S051CIMM/NOPB supports four single-ended analog input channels: IN1, IN2, IN3, and IN4. Channel selection is controlled dynamically via the 3-bit ADD2:ADD0 field in the 8-bit control register loaded on DIN. Each conversion frame specifies the input channel for the *next* conversion - for example, writing '010' selects IN3 for the subsequent sample. The default channel after power-up is IN1, and no dummy conversions or initialization delay is required.
What is the minimum and maximum SCLK frequency supported by ADC124S051CIMM/NOPB?
ADC124S051CIMM/NOPB supports an SCLK frequency range of 50 kHz to 16 MHz, as defined in the Operating Ratings. For guaranteed electrical performance (including INL, SNR, and timing margins), the datasheet specifies 3.2 MHz to 8 MHz under standard test conditions. Operation outside this range may still function but is not ensured - for example, at 50 kHz, throughput drops below 200 ksps, and at 16 MHz, timing margins tighten, potentially affecting DOUT setup/hold compliance unless layout and drive strength are optimized.
Can ADC124S051CIMM/NOPB perform continuous conversions without gaps between frames?
Yes, ADC124S051CIMM/NOPB supports continuous conversion mode. When CS remains low and SCLK continues uninterrupted, the device automatically cycles through track (3 SCLK) → hold/convert/readout (13 SCLK) → repeat. Each 16-SCLK frame delivers one 12-bit result on DOUT. There is no mandatory inter-frame delay - the next conversion begins immediately after the 16th SCLK rising edge, provided CS stays asserted. This enables deterministic, gapless sampling at up to 500 ksps (e.g., 8 MHz SCLK ÷ 16 = 500 ksps).
