Product details
Overview
TLC5510AINS from Texas Instruments is a CMOS 8-bit, 20 MSPS analog-to-digital converter (ADC) with semiflash architecture, 4-V full-scale input range, ±0.75 LSB integral linearity at 25°C, and 5-V single-supply operation - designed for high-speed video digitization in digital TV and medical imaging systems.
For engineers reviewing the TLC5510AINS datasheet, TLC5510AINS pinout, TLC5510AINS application, or TLC5510AINS equivalent, this page delivers verified technical context, package-specific terminal roles, real-world use-value metrics (e.g., 14 MHz analog bandwidth, 30 ps aperture jitter), and validated alternative options for system-level ADC selection.
Technical Context
The TLC5510AINS implements a 2-step semiflash conversion architecture with upper and lower 4-bit comparator blocks, achieving 20 MSPS throughput while reducing die size and power versus full-flash designs. Its internal reference resistor network (270 Ω nominal) supports 4-V full-scale operation when REFT is externally biased to 4 V and REFB grounded.
Latency is fixed at 2.5 clock cycles from sampling edge to valid D1–D8 output. The device features parallel CMOS-compatible outputs with tri-state control via OE, and separate analog (VDDA/AGND) and digital (VDDD/DGND) supply domains to minimize noise coupling in mixed-signal systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - delivers 256 discrete digital codes across full-scale input range. |
| Max Conversion Rate | 20 MSPS - supports real-time digitization of NTSC video signals and QAM demodulator baseband waveforms. |
| Analog Input Range | 0 V to 4 V - enables direct interface with 4-Vpp video sources without external level-shifting. |
| Integral Nonlinearity | ±0.75 LSB max at 25°C - ensures <0.3% code-dependent gain error in precision amplitude measurement. |
| Analog Bandwidth | 14 MHz (–1 dB) - preserves fidelity of composite video harmonics up to 5th order. |
| Aperture Jitter | 30 ps - limits SNR degradation to ≤46 dB at 1 MHz input, critical for low-noise medical imaging front-ends. |
| Supply Voltage | 4.75 V to 5.25 V - compatible with standard 5-V industrial and broadcast equipment rails. |
Pinout & Package
SOP (NS) 24-pin small-outline package with 0.65 mm lead pitch, 7.9 mm × 4.5 mm body, and Level-1 MSL rating (260°C reflow unlimited). Pin 1 index located at top-left corner per JEDEC MO-153.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ANALOG IN (19) | Analog input | Single-ended voltage input referenced to AGND; requires ≤10 Ω source impedance for full SFDR performance. |
| CLK (12) | Clock input | Asynchronous sampling trigger; minimum 25 ns high/low pulse width required for reliable 20 MSPS operation. |
| OE (1) | Output enable | Active-low control: drives D1–D8 into high-impedance state within 7 ns when asserted high. |
| D1–D8 (3–10) | Digital outputs | Parallel CMOS outputs; D1 = LSB, D8 = MSB; 2.5 ns enable delay and 30 ns max propagation to valid data. |
| VDDA (14,15,18) | Analog supply | 5-V analog domain rail; must be decoupled with 1-µF + 0.01-µF ceramics adjacent to pins to suppress sampling noise. |
| VDDD (11,13) | Digital supply | 5-V digital domain rail; isolated from VDDA except through internal substrate - requires separate ground plane routing. |
| REFT (17), REFBS (22) | Reference top | For TLC5510AINS: REFT accepts 4-V external reference; REFBS tied to ground to configure 4-V full-scale mode. |
| REFB (23), REFTS (16) | Reference bottom | REFB grounded; REFTS left unconnected or tied to VDDA per Figure 4 - establishes 4-V differential reference span. |
| AGND (20,21), DGND (2,24) | Analog/digital ground | Internally connected but must be joined externally at single point near device; AGND traces shield ANALOG IN on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Internal resistor reference network | 270 Ω nominal divider enables precise 4-V full-scale configuration without external resistors - reduces BOM count and layout area. |
| Tri-state parallel outputs | OE-controlled high-impedance mode allows direct connection to shared data buses without external buffers - simplifies FPGA/microprocessor interfacing. |
| 2.5-clock-cycle latency | Predictable, fixed pipeline delay enables deterministic timing alignment in synchronous video processing chains - eliminates need for FIFO-based deskew. |
| 14 MHz analog bandwidth | Supports digitization of NTSC/PAL luminance signals and QAM IF waveforms without aliasing filters - lowers system component cost. |
| 30 ps aperture jitter | Minimizes sampling uncertainty-induced noise floor elevation - maintains ≥44 dB SNR over full 0–4 V input range at 1 MHz. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9280ARSZ | 8-bit, 32 MSPS, 3.3-V supply, internal 1.25-V reference; no 4-V input option. | Requires external op-amp gain stage for 4-Vpp signals; higher speed suits broadband comms, not video-optimized. | Select when system uses 3.3-V logic and needs >20 MSPS - add gain/level-shift circuitry for 4-V inputs. |
| MAX1186EEE+ | 8-bit, 20 MSPS, 5-V supply, 2-V full-scale only; no 4-V mode or internal resistor divider. | Limited to 2-Vpp inputs; lacks REFT/REFB pin flexibility - incompatible with 4-V video standards without external scaling. | Choose only if legacy 2-Vpp design exists; cannot substitute directly for TLC5510AINS's 4-V native interface. |
Compared with AD9280ARSZ and MAX1186EEE+, the TLC5510AINS uniquely integrates 4-V full-scale operation with internal resistor referencing - eliminating external gain stages and trimming components required by alternatives, thereby reducing board area and calibration complexity in broadcast and medical video systems.

FAQ
What is the full-scale input voltage range of the TLC5510AINS?
The TLC5510AINS has a 4-V full-scale input range (0 V to 4 V), achieved by applying an external 4-V reference to REFT while grounding REFB. This configuration is explicitly defined in the datasheet's "Available Options" table and Figure 4, distinguishing it from the 2-V-range TLC5510 variant.
Does the TLC5510AINS require external reference resistors?
No - the TLC5510AINS uses its internal 270 Ω resistor divider (plus 320 Ω and 80 Ω segments) to establish the 4-V reference span. External resistors are unnecessary; only proper REFT/REFB/REFBS connections per Figure 4 are required to activate the 4-V mode in the TLC5510AINS.
What is the maximum operating temperature range for the TLC5510AINS?
The TLC5510AINS is characterized for operation from –20°C to 75°C, as confirmed in the "Available Options" table and "Recommended Operating Conditions" section of the SLAS095L datasheet. This range applies specifically to the TLC5510AINS part number, not the broader TLC5510 family.
How does the TLC5510AINS differ from the TLC5510INS?
The TLC5510AINS is the 4-V full-scale version with internal resistor network configured for 4-V operation, whereas the TLC5510INS is the 2-V full-scale variant using the same internal divider for 2-V span. Their pinouts and packages are identical, but reference terminal biasing and input range differ fundamentally.
Is the TLC5510AINS pin-compatible with Sony CXD1175?
No - the datasheet states "TLC5510 is interchangeable with Sony CXD1175", referring only to the 2-V TLC5510 variant (e.g., TLC5510INS), not the TLC5510AINS. The TLC5510AINS has different reference configuration requirements and is not documented as drop-in compatible with CXD1175.
