Product details
Overview
ADS7883SBDBVR 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 ADS7883SBDBVR datasheet, ADS7883SBDBVR pinout, ADS7883SBDBVR application, or ADS7883SBDBVR equivalent, this page provides verified electrical specs, SOT23-6 terminal mapping, real-world use scenarios, and two validated alternative parts for signal chain design continuity.
Technical Context
The ADS7883SBDBVR 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. Its zero-latency conversion enables deterministic timing in feedback loops.
It supports dual throughput modes: 2 MSPS at 2.7–4.5 V supply and 3 MSPS at 4.5–5.5 V, with acquisition time as low as 52 ns at 5 V. Digital inputs tolerate up to 5.5 V independent of VDD, easing level-shifting in mixed-supply systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - guarantees 4096 discrete output codes for precision measurement applications. |
| Sample Rate | 3 MSPS at 4.5–5.5 V - enables capture of signals up to 1.5 MHz Nyquist bandwidth in high-speed data acquisition. |
| INL / DNL | ±0.6 LSB / ±0.5 LSB - ensures monotonicity and <0.015% full-scale linearity error for accurate sensor digitization. |
| SINAD / THD | 72 dB / –84 dB at 100 kHz - supports >11.5 effective number of bits (ENOB) in clean signal environments. |
| Supply Range | 2.7 V to 5.5 V - allows direct interfacing with 3.3 V and 5 V logic domains without external regulators. |
| Power-Down Current | 1 µA - reduces system standby power in battery-operated instrumentation and portable medical devices. |
| Input Bandwidth | 30 MHz at –3 dB - accommodates wideband analog front-ends including RF baseband and optical sensor outputs. |
Pinout & Package
ADS7883SBDBVR is housed in a 6-pin SOT-23 (DBV) package, 1.45 mm maximum height, RoHS-compliant, MSL Level-2-260°C-1 year, with part marking "7883".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Power supply and internal reference source | Supplies core ADC and sets full-scale input range (0 V to VDD); must be decoupled with 1 µF + 10 nF capacitors. |
| GND (Pin 2) | Analog/digital ground reference | Common return for all analog inputs, digital I/O, and supply; requires low-impedance PCB connection to minimize noise coupling. |
| VIN (Pin 3) | Analog input signal node | Unipolar input accepting 0 V to VDD; requires ≤200 Ω source impedance or buffer (e.g., THS4031) for rated performance. |
| SCLK (Pin 4) | Serial clock input | Accepts up to 48 MHz clock (at 5 V); controls conversion timing and serial data output edges; CMOS-compatible. |
| SDO (Pin 5) | Serial data output | 3-state, MSB-first 12-bit output with two leading and two trailing zeros; VOH/VOL referenced to VDD. |
| CS (Pin 6) | Chip select (active-low) | Falling edge initiates sampling and conversion; high level places SDO in 3-state; used to enter/exit power-down mode. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-latency conversion | Eliminates pipeline delay, enabling real-time feedback in motor current sensing and closed-loop control systems. |
| Wide digital input voltage tolerance | Digital inputs accept up to 5.5 V regardless of VDD (down to 2.7 V), simplifying interface with higher-voltage controllers. |
| Low-power static operation | 2 mA typical supply current at 3 V / 2 MSPS - extends battery life in portable medical and industrial handheld instruments. |
| On-chip reference derived from VDD | Removes need for external reference IC, reducing BOM count and board space in cost-sensitive sensor nodes. |
| Industrial temperature range | Specified from –40°C to +125°C - supports deployment in under-hood automotive, industrial motor drives, and telecom infrastructure. |

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 |
|---|---|---|---|
| ADS7886IDBVR | 12-bit, 1.25 MSPS, 1.2–3.6 V supply, ±0.5 LSB INL, 65 dB SINAD | Lower speed and narrower supply range; suited for ultra-low-voltage portable sensors, not high-speed control loops | Select when operating below 2.7 V or prioritizing sub-1-mW static power over throughput. |
| ADS7884IDBVR | 12-bit, 3 MSPS, 2.7–5.5 V supply, ±1 LSB INL, 70 dB SINAD, 8-bit variant also available | Relaxed linearity and SNR specs; optimized for cost-sensitive industrial monitoring where 11.5 ENOB suffices | Choose for non-critical measurements like HVAC sensor fusion where ADS7883SBDBVR's 72 dB SINAD is over-specified. |
Compared with ADS7883SBDBVR, ADS7886IDBVR trades speed and supply flexibility for lower-voltage operation, while ADS7884IDBVR offers identical speed and supply range but with reduced AC performance-making both viable for less demanding signal chains where cost or voltage headroom drive selection.

FAQ
What is the maximum SCLK frequency supported by ADS7883SBDBVR?
The ADS7883SBDBVR supports up to 48 MHz SCLK when powered from 4.5 V to 5.5 V, and up to 32 MHz at 2.7 V to 4.5 V. This timing directly determines the 3-MSPS or 2-MSPS throughput modes. Exceeding these frequencies risks invalid data or timing violations, as confirmed in the Electrical Specifications table under "Frequency, SCLK".
Does ADS7883SBDBVR require an external voltage reference?
No, ADS7883SBDBVR uses an internal reference derived from VDD, eliminating the need for an external reference IC. Its full-scale input range is 0 V to VDD, and all DC accuracy specs-including offset and gain error-are specified relative to this internally generated reference, as stated in the Electrical Specifications and APPLICATION INFORMATION sections.
How does the power-down mode function on ADS7883SBDBVR?
The ADS7883SBDBVR enters power-down mode when CS goes high between the 2nd and 10th SCLK falling edges of a conversion frame. Power-down current drops to 1 µA, and SDO enters 3-state. Recovery requires a dummy cycle (>10 SCLK edges) and 0.8 µs power-up time before valid conversion resumes, per Figure 22 and Figure 23 of the datasheet.
What is the guaranteed missing-code performance of ADS7883SBDBVR?
The ADS7883SBDBVR (suffix "SB") guarantees no missing codes across its full 12-bit range, as explicitly stated in the ELECTRICAL SPECIFICATIONS table under "SYSTEM PERFORMANCE" and confirmed in the FEATURES section. This ensures monotonic behavior essential for closed-loop control stability and precise sensor linearization.
Can ADS7883SBDBVR interface directly with a 5-V microcontroller while operating from a 3-V supply?
Yes. The ADS7883SBDBVR digital inputs (CS, SCLK) accept voltages up to 5.5 V regardless of VDD, allowing direct connection to 5-V logic without level shifters. However, its digital output (SDO) swings from 0 V to VDD (3 V), so a level translator or 3.3-V–tolerant MCU input is required for reliable readback, as detailed in the DIGITAL INPUT/OUTPUT specifications.
