Product details
Overview
ADC104S051CIMM/NOPB from Texas Instruments is a 10-bit, 4-channel successive-approximation ADC with serial SPI-compatible interface, operating at 200–500 ksps sample rates, 2.7–5.25 V single supply, and −40°C to +85°C industrial temperature range. It integrates internal track-and-hold and multiplexer for IN1–IN4 analog inputs, delivering 62.7 dB SNR and ±0.13 LSB DNL in portable instrumentation systems.
For engineers reviewing the ADC104S051CIMM/NOPB datasheet, ADC104S051CIMM/NOPB pinout, ADC104S051CIMM/NOPB application, or ADC104S051CIMM/NOPB equivalent, key selection criteria include guaranteed no missing codes over full temperature range, channel-to-channel crosstalk of −87 dB, power-down current as low as 30 nA at 3.6 V, and compatibility with microprocessor/DSP serial interfaces requiring MSB-first straight-binary output.
Technical Context
The ADC104S051CIMM/NOPB employs a charge-redistribution DAC architecture with internal track-and-hold, acquiring input voltage during first 3 SCLK cycles after CS assertion and completing conversion in 13 additional SCLK cycles (total 16 per frame). Its multiplexer selects one of four analog inputs (IN1–IN4) via 3-bit control register loaded on DIN during each frame.
It operates fully specified across 200–500 ksps - not just at a single rate - and delivers straight-binary output synchronized to falling SCLK edges on DOUT. The device uses VA as both supply and reference, making supply noise rejection critical; its analog input capacitance is 33 pF in track mode and 3 pF in hold mode, demanding low-impedance driving sources for optimal AC performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit with guaranteed no missing codes - ensures monotonicity and deterministic code transitions across full operating range. |
| Sample Rate Range | 200–500 ksps - enables flexible throughput tuning without requalification; throughput time fixed at 16 SCLK cycles. |
| INL / DNL | +0.20/−0.10 LSB typ / ±0.13 LSB typ - supports high-accuracy DC measurements in sensor front-ends and control loops. |
| SNR | 62.7 dB typ at 40.2 kHz input - sufficient for 10-bit ENOB (9.8 bits min) in medium-bandwidth signal acquisition. |
| Power Consumption | 2.7 mW at 3 V / 8.6 mW at 5 V in normal mode; 0.11 µW at 3.6 V in shutdown - enables battery-powered operation with rapid wake-up. |
| Analog Input Range | 0 V to VA - eliminates need for external reference; requires clean, well-bypassed VA rail (1 µF + 0.1 µF). |
| Serial Interface | SPI/QSPI/MICROWIRE-compatible, MSB-first, 10-bit straight binary - interoperable with standard MCU/DSP peripherals without protocol translation. |
Pinout & Package
ADC104S051CIMM/NOPB is housed in a 10-lead VSSOP (Very Small Outline Package) with 0.5 mm lead pitch, optimized for space-constrained PCB layouts and thermal performance (θJA = 190°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - CS | Chip Select | Falling edge initiates conversion frame; high state places device in 0.11 µW shutdown mode and tri-states DOUT. |
| 2 - VA | Analog Supply | +2.7 V to +5.25 V supply and reference; must be bypassed within 1 cm with 1 µF + 0.1 µF capacitors. |
| 3 - GND | Analog Ground | Common return for analog signals and supply; separate AGND routing recommended to minimize noise coupling. |
| 4–7 - IN1 to IN4 | Analog Inputs | Four single-ended inputs; voltage range 0 V to VA; ESD-protected but not for clamping - avoid exceeding VA + 0.3 V or GND − 0.3 V. |
| 8 - DIN | Digital Input | Loads 8-bit control register on rising SCLK edges; bits ADD2–ADD0 select next channel (IN1–IN4) during each frame. |
| 9 - DOUT | Digital Output | MSB-first serial data output; active only when CS is low; outputs 10-bit result starting on 5th SCLK falling edge. |
| 10 - SCLK | Serial Clock | Drives conversion timing and data transfer; functional range 50 kHz to 16 MHz; duty cycle 30–70%. |
Key Features
| Feature | Design Value |
|---|---|
| Four-channel multiplexed input | Reduces system component count by integrating 4-input MUX and T/H - eliminates need for external analog switching or buffering in multi-sensor nodes. |
| Variable power management | Dynamic power scaling: 2.7 mW at 3 V → 0.11 µW shutdown; enables duty-cycled sensing in energy-constrained IoT endpoints. |
| Full specification over 200–500 ksps | Guaranteed DNL ±0.5 LSB, INL ±0.6 LSB, and SNR ≥61.3 dB across entire sample rate range - simplifies design validation for variable-rate applications. |
| Channel-to-channel crosstalk | −87 dB - prevents signal leakage between IN1–IN4, critical for simultaneous sampling of isolated sensors (e.g., thermocouple + pressure + humidity). |
| Single-supply operation | 2.7–5.25 V operation with VA as reference - removes need for precision external reference and reduces BOM cost in portable systems. |

FAQ
What is the maximum clock frequency supported by ADC104S051CIMM/NOPB?
The ADC104S051CIMM/NOPB supports SCLK frequencies from 50 kHz to 16 MHz, with guaranteed AC performance (e.g., SNR ≥61.3 dB) specified over 3.2–8 MHz. Operation beyond 8 MHz remains functional but falls outside ensured specifications; timing margins must be verified per application conditions.
Does ADC104S051CIMM/NOPB require an external reference voltage?
No, ADC104S051CIMM/NOPB uses VA as both supply and reference - its full-scale range is 0 V to VA. This eliminates the need for an external reference, reducing BOM count and layout complexity, though VA must be low-noise and well-bypassed to maintain 62.7 dB SNR performance.
How does the ADC104S051CIMM/NOPB handle channel selection during continuous conversion?
The ADC104S051CIMM/NOPB loads the next channel address via DIN during each 16-cycle frame. Bits ADD2–ADD0 in the 8-bit control register determine whether IN1–IN4 is sampled in the subsequent conversion cycle, enabling programmable sequencing without host intervention between frames.
What is the power-down current of ADC104S051CIMM/NOPB at 3.6 V?
At 3.6 V supply and TA = 25°C, the ADC104S051CIMM/NOPB draws 30 nA in shutdown mode (CS high), dropping to 0.11 µW total power consumption - ideal for battery-operated systems requiring microamp-level quiescent current between measurements.
Is ADC104S051CIMM/NOPB compatible with standard SPI interfaces?
Yes, ADC104S051CIMM/NOPB is SPI-compatible: it accepts MSB-first straight-binary data on DIN with rising SCLK edges, outputs converted data on DOUT aligned to falling SCLK edges, and uses CS as frame sync - requiring no mode configuration or level-shifting for direct connection to common MCU SPI peripherals.
