Texas Instruments TLC5510AINSR

Overview

TLC5510AINSR from Texas Instruments is a CMOS 8-bit, 20 MSPS analog-to-digital converter (ADC) using a semiflash architecture for high-speed video and communications signal digitization. It features 4-V full-scale input range, ±0.75 LSB integral nonlinearity at 25°C, and 5-V single-supply operation - enabling direct integration into digital TV front-ends and QAM demodulator signal chains.

For engineers reviewing the TLC5510AINSR datasheet, TLC5510AINSR pinout, TLC5510AINSR application, or TLC5510AINSR equivalent, this page delivers verified technical context, real-world timing behavior (2.5-clock latency), differential linearity performance (±0.5 LSB at 25°C), and validated SOP-24 package implementation details - all critical for high-fidelity sampling in medical imaging and video conferencing systems.

Technical Context

The TLC5510AINSR implements a two-step semiflash conversion architecture with upper and lower 4-bit comparator blocks, reducing comparator count versus full-flash designs while maintaining 20 MSPS throughput. Its internal reference resistor divider is configured for 4-V full-scale operation via external REFT (4 V) and REFB (GND) connections, eliminating need for external precision references.

Latency is fixed at 2.5 clock cycles from analog sampling to valid D1–D8 output, with parallel CMOS-compatible outputs supporting high-impedance mode via OE control. Analog input bandwidth is 14 MHz (–1 dB), aperture jitter is 30 ps, and differential gain/phase are specified at 1% and 0.7° under NTSC ramp conditions - confirming suitability for broadcast-grade video digitization.

FAQ

What is the full-scale input voltage range of the TLC5510AINSR?

The TLC5510AINSR has a 4-V full-scale input range (0 V to 4 V), achieved by applying 4 V to REFT and grounding REFB. This configuration uses the internal 270 Ω reference resistor and eliminates external reference components - a key differentiator from the 2-V-range TLC5510 variant. The TLC5510AINSR maintains ±0.75 LSB integral nonlinearity across –20°C to 75°C.

Does the TLC5510AINSR require an external reference voltage source?

No, the TLC5510AINSR does not require an external reference IC. It uses its internal 270 Ω resistor between REFT and REFB, with 4 V applied to REFT and REFB grounded. This creates a precise 4-V reference span. External jumpers (not components) configure the reference path - confirmed in TI's SLAS095L datasheet Figure 4 and "internal referencing" section.

What is the latency from analog input sampling to valid digital output on the TLC5510AINSR?

The TLC5510AINSR exhibits a fixed 2.5-clock-cycle latency from the falling edge of CLK (sampling instant) to valid D1–D8 output. This is inherent to its semiflash architecture and documented in the functional timing diagram (Figure 2) and operating characteristics table (page 5). Latency remains constant regardless of input frequency or temperature.

Can the TLC5510AINSR drive FPGA or ASIC inputs directly?

Yes, the TLC5510AINSR's parallel CMOS outputs (D1–D8) drive standard 5-V logic interfaces directly. Each output provides 2.5 mA sink current (IOL) and –1.5 mA source current (IOH), compatible with FPGA I/O banks configured for 5-V tolerant or LVTTL standards. OE control allows clean bus sharing without external buffers.

Is the TLC5510AINSR pin-compatible with the TLC5510INSR?

Yes, the TLC5510AINSR and TLC5510INSR share identical SOP-24 (NS) packaging, pinout, and footprint. However, they differ electrically: TLC5510AINSR is the 4-V full-scale variant (TLC5510A), while TLC5510INSR is the 2-V variant (TLC5510). Reference connections (REFT/REFB) and linearity specs differ - direct substitution requires schematic and layout review.
