Product details
Overview
ADS7883SDBVR from Texas Instruments is a 12-bit, 3-MSPS successive approximation register (SAR) analog-to-digital converter with zero latency, 48-MHz serial interface, and unipolar 0 V to VDD input range. It operates from 2.7 V to 5.5 V, delivers ±0.6 LSB INL and 72 dB SINAD at 100 kHz, and targets high-speed closed-loop control in motor drives and optical networking systems.
For engineers reviewing the ADS7883SDBVR datasheet, ADS7883SDBVR pinout, ADS7883SDBVR application, or ADS7883SDBVR equivalent, key selection criteria include its 6-pin SOT23 package, micropower operation (6.45 mW at 3 V/2 MSPS), power-down current of 1 µA, and guaranteed no missing codes across temperature.
Technical Context
The ADS7883SDBVR implements a capacitor-based SAR architecture with integrated sample-and-hold, sampling on the falling edge of CS and outputting 12-bit MSB-first data over a 3-wire SPI-compatible interface (CS, SCLK, SDO). Its zero-latency conversion enables real-time feedback in high-speed control loops without pipeline delay.
It features rail-to-rail analog input (0 V to VDD), wide digital input voltage tolerance (up to 5.5 V independent of VDD), and internal reference derived from VDD-eliminating external reference components while supporting flexible power sequencing and mixed-voltage system interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - ensures monotonicity and full code coverage for precision measurement applications. |
| Sample rate | 3 MSPS at 4.5–5.5 V VDD; 2 MSPS at 2.7–4.5 V - supports high-bandwidth signal capture while scaling power with supply. |
| SINAD / THD | 72 dB / –84 dB at 100 kHz - enables accurate digitization of medium-frequency sensor and communication signals. |
| INL / DNL | ±0.6 LSB / ±0.5 LSB - guarantees linearity critical for closed-loop control accuracy and calibration stability. |
| Power consumption | 6.45 mW at 3 V/2 MSPS; 13.5 mW at 5 V/3 MSPS - optimized for battery-powered and thermally constrained designs. |
| Input bandwidth | 30 MHz (–3 dB) - supports fast transient response and wideband sensor inputs without external buffering. |
| Power-down current | 1 µA - enables ultra-low quiescent power during idle cycles in duty-cycled systems. |
Pinout & Package
ADS7883SDBVR is housed in a 6-pin SOT23 (DBV) package, 2.9 mm × 1.6 mm × 1.45 mm, RoHS-compliant, MSL Level-2-260°C-1 year.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply and internal reference | Supplies core logic and ADC reference; determines full-scale input range (0 V to VDD); accepts 2.7–5.5 V. |
| GND | Analog/digital ground reference | Common return for all analog and digital signals; must be low-impedance and decoupled with 10-nF + 1-µF capacitors. |
| VIN | Analog input | Unipolar single-ended input; requires ≤200 Ω source impedance for rated performance; no external reference needed. |
| SCLK | Serial clock input | CMOS-compatible clock up to 48 MHz; controls conversion timing and data shift-out; supports variable frequency operation. |
| SDO | Serial data output | 3-state, MSB-first 12-bit output with two leading and two trailing zeros; level referenced to VDD. |
| CS | Chip select (active low) | Initiates sampling on falling edge; controls power-down entry/exit; must remain low for full 16-clock frame for valid data. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-latency SAR architecture | Eliminates pipeline delay - enables immediate feedback in servo loops and real-time control without phase lag. |
| Digital input voltage tolerance | Accepts up to 5.5 V digital inputs even at 2.7 V VDD - simplifies level-shifting in mixed-supply systems and eases power-up sequencing. |
| Wide supply range | 2.7 V to 5.5 V operation - supports direct integration with 3.3 V and 5 V microcontrollers, battery rails, and industrial supplies. |
| On-chip sample-and-hold | Integrated capacitor-based sampling circuit - removes need for external S/H amplifier and reduces board area and BOM count. |
| Low-power power-down mode | 1 µA shutdown current with 0.1 µs wake-up time - ideal for intermittent sensing and energy harvesting applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7884SDBVR | 10-bit resolution, ±2 LSB INL, 3 MSPS max at 4.5–5.5 V only - lower precision but identical package and interface. | Lower-resolution sensing where 10-bit linearity suffices (e.g., basic voltage monitoring, non-critical feedback). | Select when cost sensitivity outweighs resolution requirements and system SNR budget allows ≥12 dB reduction. |
| ADS7886SDBVR | 12-bit, 1.25 MSPS, 1.2–3.6 V supply - lower speed, narrower voltage range, but superior low-voltage operation. | Ultra-low-voltage embedded systems (e.g., coin-cell IoT nodes) where 3-MSPS throughput is unnecessary. | Choose for sub-2 V supply compatibility and reduced power at <2 MSPS; avoid if >2.5 MSPS or >3.6 V operation required. |
Compared with ADS7883SDBVR, ADS7884SDBVR trades resolution for cost and ADS7886SDBVR trades speed and voltage range for ultra-low-voltage capability - neither offers pin-to-pin or functional equivalence, but both serve adjacent design points in TI's micropower SAR family.

FAQ
What is the maximum sample rate of the ADS7883SDBVR and under what conditions?
The ADS7883SDBVR achieves a maximum sample rate of 3 MSPS when powered from 4.5 V to 5.5 V VDD and driven with a 48-MHz SCLK. At 2.7 V to 4.5 V VDD, the maximum rate is 2 MSPS using a 32-MHz SCLK. This voltage-dependent throughput is explicitly specified in the Electrical Characteristics table and validated across –40°C to 125°C.
Does the ADS7883SDBVR require an external voltage reference?
No, the ADS7883SDBVR uses its VDD supply as the internal reference for the ADC, enabling a fully self-contained 12-bit conversion solution with no external reference components. The unipolar input range is 0 V to VDD, and full-scale accuracy is maintained across the 2.7 V to 5.5 V supply range per the datasheet specifications.
What is the power-down current specification for the ADS7883SDBVR?
The ADS7883SDBVR draws 1 µA in power-down state, as confirmed in the Electrical Specifications table under "Power-down state supply current." This ultra-low quiescent current is guaranteed over the full operating temperature range (–40°C to 125°C) and enables aggressive power gating in battery-sensitive applications.
Can the ADS7883SDBVR interface directly with a 5-V microcontroller while operating from a 3-V supply?
Yes - the ADS7883SDBVR supports digital input voltages up to 5.5 V regardless of VDD level, allowing direct connection to 5-V logic without level shifters. However, its digital output levels (VOH/VOL) remain referenced to its own VDD, so 3-V SDO signaling must be interpreted by a 3-V-tolerant MCU input or buffered appropriately.
What package type and markings identify the ADS7883SDBVR?
The ADS7883SDBVR is supplied in a 6-pin SOT23 (DBV) package with standard JEDEC MO-178 outline, marked "7883" on the top surface. It is RoHS-compliant, moisture-sensitivity level 2 (260°C peak reflow), and shipped in large tape-and-reel format (3000 units per reel), as documented in TI's Package Option Addendum.
