Product details
Overview
ADS930E from Texas Instruments is an 8-bit, 30 MSPS pipelined analog-to-digital converter (ADC) with internal reference, single-ended 1V–2V input range, 46 dB SNR at 12 MHz, ±0.4 LSB DNL, and SSOP-28 package. It delivers high-speed digitization for video signal chains and portable test instrumentation requiring low-power, high-linearity sampling.
For engineers reviewing the ADS930E datasheet, ADS930E pinout, ADS930E application, or ADS930E equivalent, this page provides verified technical context, real-world timing behavior, confirmed digital interface logic levels, validated power-down latency, and precise differential linearity performance across temperature - all specific to the ADS930E variant.
Technical Context
The ADS930E implements a 7-stage pipeline architecture with 2-bit quantizers per stage and digital error correction to guarantee no missing codes and ±0.4 LSB DNL. Its track-and-hold operates with aperture jitter of 7 ps rms and supports both single-ended (IN tied to CM) and differential input configurations.
It integrates a resistor-ladder-based internal reference generating +1.25 V (REFB), +1.75 V (REFT), and derived +1.5 V common-mode voltage (CM), with dedicated bypass pins (LpBy, LnBy) and unbuffered +1VREF output. Digital outputs use TTL/HCT-compatible CMOS logic with LVDD-supplied drivers and 5-clock-cycle data latency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - delivers 256 discrete output codes with guaranteed no missing codes across full operating temperature range. |
| Sampling Rate | 30 MSPS - supports real-time digitization of baseband video and IF signals up to 15 MHz Nyquist bandwidth. |
| SNR | 46 dB at 500 kHz input - enables >7 effective bits of dynamic resolution for precision measurement applications. |
| DNL | ±0.4 LSB max at 500 kHz and 12 MHz - ensures monotonic transfer function critical for imaging and communications systems. |
| Power Dissipation | 66 mW at +3 V - allows battery-powered operation in camcorders and portable test equipment without thermal derating. |
| Analog Input Bandwidth | 100 MHz full-power - supports accurate digitization of fast-rising video edges and composite sync pulses. |
| Aperture Jitter | 7 ps rms - limits SNR degradation to ≤0.5 dB at 12 MHz input, enabling stable performance in undersampling architectures. |
Pinout & Package
ADS930E is housed in a 28-pin SSOP (DB) package with 0.65 mm pitch, moisture sensitivity level 2 (260°C, 1 year), and RoHS-compliant NiPdAu lead finish. Thermal resistance θJA is 89°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 18, 28 (+VS) | Analog supply input | Accepts +2.7 V to +5.25 V; internally connected to all analog circuitry including T/H, reference ladder, and quantizer stages. |
| 2 (LVDD) | Digital output driver supply | Independent 2.7–5.25 V rail sets VOH/VOL thresholds; decoupling required to prevent digital noise coupling into analog sections. |
| 15 (CLK) | Convert clock input | Rising-edge-triggered; supports 33 ns minimum period (30 MSPS); tolerant to ±10% duty cycle variation but requires <2 ns rise/fall for full spec compliance. |
| 16 (OE) | Output enable (active low) | Drives all 8 data outputs to high-impedance when high; internal pull-down allows floating operation in normal mode. |
| 17 (Pwrdn) | Power-down control | Logic high disables conversion and reduces supply current by ~70%; outputs enter 3-state; 5-clock-cycle invalid data follows exit. |
| 23 (1VREF) | Unbuffered 1 V reference output | Derived from internal ladder; not buffered - must remain unloaded or externally buffered to avoid reference perturbation. |
| 26 (CM) | Common-mode voltage output | Midpoint of internal reference ladder (+1.5 V typical); used to bias single-ended inputs or level-shift external drivers. |
| 27 (+IN), 24 (IN) | Differential analog inputs | +IN accepts 1 V–2 V single-ended signal when IN is tied to CM; full-scale differential swing is 0.5 Vp-p. |
Key Features
| Feature | Design Value |
|---|---|
| Digital error correction | Guarantees no missing codes and ±0.4 LSB DNL across –40°C to +85°C, eliminating calibration requirements in production imaging systems. |
| Internal reference ladder | Provides stable +1.25 V (REFB), +1.75 V (REFT), and +1.5 V (CM) without external components - reduces BOM count and layout complexity. |
| Single-supply compatibility | Operates from +3 V or +5 V with ±10% tolerance; 66 mW power at +3 V enables direct integration into 3.3 V system rails. |
| 5-clock-cycle data latency | Predictable, fixed delay from CLK edge to valid SOB output - simplifies timing closure in synchronous FPGA or ASIC interfaces. |
| SSOP-28 thermal performance | θJA = 89°C/W with standard PCB copper; supports continuous 30 MSPS operation in sealed portable enclosures up to +85°C ambient. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit, 30 MSPS ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9203ARUZ | 3 V-only supply; 105 mW power at 40 MSPS; 0.5 LSB DNL; TSSOP-28 package. | Higher power and slightly relaxed DNL; optimized for RF IF sampling rather than video/composite signal fidelity. | Choose AD9203ARUZ when higher sampling rate (40 MSPS) and tighter SFDR (>65 dBc) outweigh SNR and differential linearity requirements. |
| MAX1186ETI+ | +5 V supply only; 125 mW at 20 MSPS; ±0.5 LSB DNL; 28-pin TQFN package; no internal reference. | Requires external reference and voltage translation for 3 V logic; better suited for industrial control over portable video. | Choose MAX1186ETI+ when board space constraints favor TQFN and system already provides precision +2.5 V reference. |
Compared with AD9203ARUZ and MAX1186ETI+, the ADS930E uniquely combines internal reference, 3V/5V dual-supply flexibility, 46 dB SNR at 12 MHz, and ±0.4 LSB DNL in SSOP-28 - making it optimal for cost-sensitive, battery-powered video digitization where reference integration and low DNL are non-negotiable.

FAQ
What is the maximum sampling rate supported by the ADS930E?
The ADS930E is fully specified for operation at 30 MSPS, with a minimum convert clock period of 33 ns. At this rate, it maintains 46 dB SNR at 500 kHz input and ±0.4 LSB DNL across –40°C to +85°C. Operation beyond 30 MSPS is not characterized and may degrade integral nonlinearity or increase missing code risk in the ADS930E.
Does the ADS930E require an external reference voltage?
No, the ADS930E does not require an external reference. It integrates a precision resistor ladder that generates +1.25 V (REFB), +1.75 V (REFT), and +1.5 V (CM) internally. Pin 23 (1VREF) provides an unbuffered 1 V output derived from the ladder, but the ADS930E functions fully with only +VS and LVDD supplies connected.
How many clock cycles of latency does the ADS930E exhibit between sampling and valid output data?
The ADS930E exhibits exactly 5 clock cycles of data latency from the rising edge of the CLK signal to valid straight offset binary output on pins 5–12. This latency is fixed and deterministic, enabling precise timing alignment in FPGA-based capture systems without dynamic adjustment or FIFO buffering for the ADS930E.
Can the ADS930E operate from a single +3.3 V supply?
Yes, the ADS930E supports +3 V nominal operation with ±10% tolerance (i.e., +2.7 V to +3.3 V), and its LVDD pin can be tied to the same +3.3 V rail. At +3 V, it draws 22 mA and dissipates 66 mW - making it suitable for direct connection to standard 3.3 V system supplies without regulation overhead for the ADS930E.
What is the purpose of pins 21 (LpBy) and 25 (LnBy) on the ADS930E?
Pins 21 (LpBy) and 25 (LnBy) connect to the top and bottom nodes of the internal reference ladder and are intended for external 0.1 µF ceramic bypass capacitors. These capacitors suppress high-frequency switching noise coupled back into the reference structure, directly improving SNR and SFDR performance of the ADS930E - especially critical at 30 MSPS operation.
