Texas Instruments TLV5535IPW

Overview

TLV5535IPW from Texas Instruments is an 8-bit, 35 MSPS analog-to-digital converter optimized for IF sampling and high-speed DSP front-ends. It features 3.3-V single-supply operation, 90 mW typical power dissipation with internal references disabled, 600 MHz analog input bandwidth, and 3.3-V TTL/CMOS-compatible digital I/O. It serves as a digitization engine in communication receivers and video signal chains.

For engineers reviewing the TLV5535IPW datasheet, TLV5535IPW pinout, TLV5535IPW application, or TLV5535IPW equivalent, key selection considerations include its pipeline latency (4.5 clock cycles), aperture jitter (1.5 ps rms), INL (±0.7 LSB typ), SNRD (46 dB typ at 1 MHz), and support for both internal and externally adjustable voltage references.

Technical Context

The TLV5535IPW implements a single-pipeline ADC architecture with six 2-bit stages plus a final flash stage, corrected by logic that combines outputs to produce an 8-bit result with no missing codes over –40°C to 85°C. Its sampling-and-hold captures signals on each rising CLK edge, with analog input settling governed by 4 pF input capacitance and 200 Ω switch resistance.

Digital outputs are three-state, driven by separate DRVDD/DRVSS supplies to minimize noise coupling into analog sections. Reference control is decoupled: PWDN_REF independently disables internal reference generation, while STBY enables full standby mode (11–15 mW), and OE controls output buffer enablement with 5–8 ns disable/enable timing.

Key Specifications

Pinout & Package

FAQ

What is the absolute maximum analog input voltage for TLV5535IPW?

The absolute maximum analog input voltage for TLV5535IPW is AVDD + 0.5 V relative to AVSS. For example, at AVDD = 3.3 V and AVSS = 0 V, the maximum allowable AIN voltage is 3.8 V. Exceeding this risks permanent damage per the absolute maximum ratings table in the SLAS221 datasheet. Always operate within the recommended range: V(REFBI) ≤ AIN ≤ V(REFTI).

Does TLV5535IPW support differential input configuration?

No, TLV5535IPW does not support differential analog input. Its AIN pin is a single-ended input, and the device lacks internal circuitry for differential-to-single-ended conversion. The functional block diagram and input circuit schematics confirm a single-input topology. For differential applications, external op-amp conditioning or a dedicated differential-input ADC like the ADS5270 would be required.

How does the TLV5535IPW pipeline latency affect system synchronization?

The TLV5535IPW has a fixed pipeline latency of 4.5 clock cycles plus up to 9 ns output propagation delay. This means the digital output for sample N appears 4.5 CLK periods after the rising edge that sampled it. At 35 MSPS, this totals ~135 ns - requiring precise timing alignment in FPGA or DSP interfaces, especially since data is valid on the falling CLK edge due to td(o) exceeding half the clock period.

Can TLV5535IPW operate with only internal references enabled and no external components?

Yes, TLV5535IPW can operate fully with internal references: connect REFBO to REFBI and REFTO to REFTI, and place 1 µF capacitors from REFBO and REFTO to AVSS. The internal bandgap generator provides stable top/bottom references, yielding a 1.0–1.3 Vpp full-scale range depending on AVDD. No external op-amps or resistors are needed for basic operation.

What is the purpose of the CML pin on TLV5535IPW?

The CML (Common Mode Level) pin on TLV5535IPW outputs (AVDD – AVSS)/2 - a stable mid-supply voltage used for biasing ac-coupled analog inputs or as a reference for external driver circuits. An external 0.1 µF capacitor must be connected between CML and AVSS to ensure low-noise operation and prevent coupling of analog supply transients into the signal path.
