Product details
Overview
ADS7883SBDBVT 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 ADS7883SBDBVT datasheet, ADS7883SBDBVT pinout, ADS7883SBDBVT application, or ADS7883SBDBVT equivalent, this page provides verified electrical specifications, SOT23-6 terminal mapping, real-world timing behavior, and validated alternative options for battery-powered and industrial signal acquisition designs.
Technical Context
The ADS7883SBDBVT 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 deterministic timing in real-time feedback loops.
It supports dual throughput modes: 2 MSPS at 2.7–4.5 V and 3 MSPS at 4.5–5.5 V supply, 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 monotonicity and no missing codes across full temperature range (–40°C to 125°C). |
| 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 accurate amplitude fidelity in precision sensor digitization (e.g., bus voltage monitoring). |
| SINAD / THD | 72 dB / –84 dB at 100 kHz - supports clean spectral performance for baseband radio and optical sensor interfaces. |
| Supply Range | 2.7 V to 5.5 V - allows direct operation from Li-ion batteries (3.0–3.7 V) or 5-V system rails without regulation. |
| Power-Down Current | 1 µA - reduces quiescent draw during idle cycles in energy-constrained portable instrumentation. |
| Input Bandwidth | 30 MHz (–3 dB) - accommodates wideband analog front-ends without external anti-aliasing filter complexity. |
Pinout & Package
ADS7883SBDBVT is housed in a 6-pin SOT-23 (DBV) package, 1.45 mm maximum height, RoHS-compliant, MSL Level-2-260°C-1 year. Pin 1 marked via index area; Q3 pin 1 quadrant orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply & internal reference | Supplies core logic and ADC reference; also defines unipolar input span (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 | Single-ended unipolar input; requires ≤200 Ω source impedance for full AC performance; sampled on CS falling edge. |
| SCLK | Serial clock input | Accepts up to 48 MHz (5 V) or 32 MHz (2.7–4.5 V); controls conversion timing and serial data shift-out rate. |
| SDO | Serial data output | 3-state CMOS output; MSB-first 12-bit word padded with two leading and two trailing zeros; VOH/VOL referenced to VDD. |
| CS | Chip select (active low) | Initiates conversion on falling edge; asserts power-down if high between 2nd and 10th SCLK falling edges; controls SDO 3-state. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-latency conversion | Enables immediate feedback in servo loops-no pipeline delay; output valid within one SCLK cycle after CS assertion. |
| Wide digital input voltage tolerance | Digital inputs accept up to 5.5 V regardless of VDD (e.g., 2.7 V), eliminating level-shifters in multi-rail host systems. |
| Low-power static operation | Draws only 1.8 mA at 3 V in static mode-ideal for always-on sensor nodes where conversion is infrequent. |
| High-temperature grade | Specified from –40°C to +125°C-supports under-hood automotive motor control and industrial drive environments. |
| Integrated sampling circuit | On-chip capacitor DAC and comparator eliminate external sample-hold ICs, reducing BOM count and board space. |

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 |
|---|---|---|---|
| ADS7884SBDBVT | 12-bit, 3-MSPS, but wider supply (2.7–5.5 V) and higher DNL (±0.75 LSB); same SOT23-6 package. | Less precise linearity; suitable where cost sensitivity outweighs INL-critical metrology. | Select ADS7884SBDBVT only if ±0.75 LSB DNL is acceptable and lower unit cost is prioritized. |
| ADS8320EB/250 | 16-bit, 1-MSPS, SPI interface, SOIC-8; higher resolution but lower speed and larger footprint. | Targets precision DC/low-frequency sensing (e.g., strain gauges), not high-speed closed-loop control. | Choose ADS8320EB/250 when resolution >12-bit is mandatory and 1-MSPS throughput suffices. |
Compared with ADS7883SBDBVT, ADS7884SBDBVT trades linearity for cost in identical form factor, while ADS8320EB/250 sacrifices speed and size for 4-bit resolution gain-making ADS7883SBDBVT optimal for 3-MSPS, 12-bit, space-constrained industrial control.

FAQ
What is the maximum sample rate of the ADS7883SBDBVT and under what conditions?
The ADS7883SBDBVT achieves a maximum sample rate of 3 MSPS when operated with a 4.5–5.5 V supply and 48-MHz SCLK. At 2.7–4.5 V, the rated throughput drops to 2 MSPS. This dual-rate behavior is specified in the Electrical Characteristics table and confirmed by timing diagrams showing tconv = 265 ns (typ) at 5 V. The ADS7883SBDBVT maintains full 12-bit performance across both modes.
Does the ADS7883SBDBVT require an external reference voltage?
No, the ADS7883SBDBVT uses its VDD supply as the internal reference-no external reference is needed. The unipolar input range is 0 V to VDD, and the device derives its full-scale reference directly from the power rail. This simplifies design and reduces BOM count, though supply noise must be controlled using 10-nF and 1-µF decoupling capacitors per the Application Information section.
What is the power-down behavior of the ADS7883SBDBVT and how fast does it recover?
The ADS7883SBDBVT enters power-down mode when CS is pulled high between the 2nd and 10th SCLK falling edges, reducing supply current to 1 µA. Recovery requires a dummy conversion frame lasting ≥0.8 µs-equivalent to three full 3-MSPS frames. During recovery, SDO remains in 3-state and output data is invalid until full power-up completes. This behavior is explicitly defined in Figure 23 and the Timing Requirements table.
Can the ADS7883SBDBVT interface directly with a 5-V microcontroller while powered from 3 V?
Yes-the ADS7883SBDBVT digital inputs (CS, SCLK) tolerate up to 5.5 V regardless of VDD level, enabling direct connection to 5-V logic without level shifters. However, its digital output (SDO) levels are referenced to VDD, so a 3-V-powered ADS7883SBDBVT outputs VOH ≈ 2.8 V (VDD–0.2 V), which is compatible with most 5-V-tolerant MCU inputs but may require verification against the host's VIH threshold.
What package and marking does the ADS7883SBDBVT use, and how is pin 1 identified?
The ADS7883SBDBVT uses a 6-pin SOT-23 (DBV) package with maximum height of 1.45 mm and JEDEC MO-178 compliance. It is marked "7883" on the top surface. Pin 1 is located in Quadrant 3 (Q3) and identified by an index area adjacent to the lead-confirmed by TI's DBV0006A package outline and tape-and-reel documentation.
