Product details
Overview
ADS830E from Texas Instruments is an 8-bit, 60MHz pipelined analog-to-digital converter (ADC) with single-ended or differential input capability, internal/external reference selection, 1Vp-p/2Vp-p programmable input range, and SSOP-20 package. It delivers 49.5dB SNR at 1MHz and supports medical imaging, video digitizing, and high-speed communications systems requiring precise, low-distortion sampling.
For engineers reviewing the ADS830E datasheet, ADS830E pinout, ADS830E application, or ADS830E equivalent, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, confirmed alternative options, and supply support details specific to the ADS830E - not generic ADCs or family-level abstractions.
Technical Context
The ADS830E employs a 6-stage pipelined CMOS architecture with digital error correction logic to guarantee no missing codes and ±0.2LSB DNL at 10MHz. Its track-and-hold supports both single-ended and differential analog inputs, with common-mode voltage referenced to +2.5V via the CM pin or external resistive divider.
It features dual reference control: INT/EXT pin selects between internal 3.0V/2.0V references or external REFT/REFB sources, while RSEL configures full-scale range (1Vp-p or 2Vp-p). Data latency is fixed at 4 clock cycles, and outputs use straight offset binary coding with 3-state CMOS/TTL-compatible drivers powered by dedicated VDRV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8 guaranteed bits - ensures full 256-code monotonicity without missing codes in imaging/video applications. |
| Max Sampling Rate | 60MSPS - enables digitization of baseband video signals up to ~25MHz Nyquist bandwidth. |
| SNR @ 1MHz | 49.5dBFS - provides ≥7.7 effective bits for high-fidelity signal capture in medical ultrasound front-ends. |
| Differential Nonlinearity | ±0.2LSB max @ 10MHz - maintains linearity critical for disk-drive servo loop accuracy. |
| Power Dissipation | 170mW @ VDRV = 3V, external reference - allows thermal management in dense PCB layouts without forced cooling. |
| Analog Input Range | Programmable 1Vp-p or 2Vp-p - matches varying sensor output levels without external gain stages. |
| Reference Flexibility | Internal (3.0V/2.0V) or external REFT/REFB - enables multi-channel DC gain/offset matching in synchronized acquisition systems. |
Pinout & Package
ADS830E is housed in a 20-pin SSOP (DBQ) package with 0.65mm pitch, RoHS-compliant NIPDAU finish, and MSL Level-2-260°C-1 year rating. Thermal resistance θJA is 115°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 18 | GND | Analog ground reference - must connect directly to solid analog ground plane to minimize noise coupling into track/hold. |
| 2–9 | D7–D0 (MSB–LSB) | 3-state CMOS/TTL data outputs - driven by VDRV-supplied logic rail; timing-critical for interface to FPGA or DSP. |
| 10 | CLK | Rising-edge convert clock - jitter ≤1.2ps rms required to preserve 49.5dB SNR at 1MHz input. |
| 11 | RSEL | Input range select - HIGH = 2Vp-p, LOW = 1Vp-p; internal 50kΩ pull-up defaults to 2Vp-p. |
| 12 | INT/EXT | Reference source select - LOW = internal 3.0V/2.0V, HIGH = external REFT/REFB; internal 50kΩ pull-up defaults to external mode. |
| 13, 14 | REFB, REFT | Bottom/top reference pins - define full-scale range (REFT – REFB); drive external circuitry up to 1mA. |
| 15 | CM | Common-mode voltage output - unbuffered high-impedance node; used to bias external op-amps at +2.5V. |
| 16, 17 | IN, IN | Differential analog inputs - require matched external biasing; single-ended operation uses IN as signal, IN tied to CM. |
| 19 | +VS | +5V analog supply - must be decoupled with 0.1µF ceramic + 10µF bulk capacitor near pin. |
| 20 | VDRV | Digital output driver supply - set to +3V or +5V to match host logic; independent of +VS to isolate digital switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| Pipelined 6-stage architecture with digital error correction | Guarantees no missing codes and ±0.2LSB DNL at 10MHz - essential for accurate position sensing in disk-drive control. |
| Programmable 1Vp-p/2Vp-p input range via RSEL pin | Eliminates need for external gain adjustment when interfacing to diverse sensors or video amplifiers. |
| Dual reference mode (internal or external) | Enables precise inter-channel gain/offset matching in multi-ADC systems using shared external reference. |
| Dedicated VDRV output supply pin | Allows +3V logic interfacing to reduce power dissipation by 15mW vs. +5V and suppress digital noise coupling into analog section. |
| Single-ended or differential analog input topology | Supports cost-effective single-ended designs or high-SFDR differential configurations without changing PCB layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS831E | 8-bit, 80MSPS, pin-for-pin compatible but higher power (225mW), no RSEL pin - fixed 2Vp-p range. | Better suited for wideband IF sampling where speed >60MSPS is mandatory; less flexible for variable-sensor interfaces. | Select ADS831E only if 80MSPS is required and external range programming is unnecessary. |
| MAX1186EEE+ | 8-bit, 65MSPS, internal reference only, no differential input option, 24-pin QSOP package. | Designed for compact, cost-sensitive systems where board space permits larger package and reference flexibility is secondary. | Choose MAX1186EEE+ when internal reference suffices and SSOP-20 footprint is unavailable. |
Compared with ADS830E, ADS831E trades programmable input range and lower power for higher speed, while MAX1186EEE+ sacrifices reference and input topology flexibility for slightly higher sample rate in a different package - neither offers identical feature parity.

FAQ
What is the maximum sampling rate supported by the ADS830E?
The ADS830E supports a maximum sampling rate of 60 million samples per second (60MSPS), validated across its full specified temperature range (–40°C to +85°C). This rate is achievable with both internal and external reference configurations and is documented in the Electrical Characteristics table under "Sample Rate" with a typical value of 60MSPS and minimum of 10kSPS. The ADS830E maintains guaranteed 8-bit performance up to this limit.
Does the ADS830E support differential analog input?
Yes, the ADS830E supports true differential analog input via pins 16 (IN) and 17 (IN), enabling improved spurious-free dynamic range (SFDR) compared to single-ended operation. When configured differentially, the device accepts a 2Vp-p input range centered at the common-mode voltage (CM pin). The internal track-and-hold is optimized for differential signaling, and the datasheet confirms this capability in both the Description and Application Information sections.
What is the purpose of the VDRV pin on the ADS830E?
The VDRV pin on the ADS830E supplies power exclusively to the digital output drivers, allowing independent control of logic voltage levels. It can be set to +3V or +5V to interface directly with corresponding CMOS/TTL families. Using VDRV = +3V reduces power dissipation by ~15mW and minimizes digital switching noise coupling into the analog section - a design choice explicitly recommended in the datasheet for optimal AC performance.
Can the ADS830E operate with only an external reference?
Yes, the ADS830E can operate exclusively with external references applied to REFT (pin 14) and REFB (pin 13). Setting the INT/EXT pin (pin 12) HIGH disables the internal 3.0V/2.0V reference buffers. External reference voltages must satisfy: REFT between (REFB + 0.8V) and (+VS – 1.25V), and REFB between 1.25V and (REFT – 0.8V). This mode is confirmed in the Reference Operation section and Electrical Characteristics table.
What package type is used for the ADS830E?
The ADS830E is packaged in a 20-pin SSOP (Shrink Small Outline Package), also designated DBQ by Texas Instruments. It has a 0.65mm lead pitch, RoHS-compliant NIPDAU lead finish, and Moisture Sensitivity Level (MSL) rating of Level-2-260°C-1 year. This package is explicitly listed in the Package/Ordering Information table and confirmed in the Pin Configuration diagram.
