Texas Instruments OPA4830IPW

Overview

OPA4830IPW from Texas Instruments is a quad, low-power, single-supply, wideband voltage-feedback operational amplifier optimized for 3V/5V ADC input buffering and video line driving. It delivers 230MHz bandwidth at G=+1, 560V/μs slew rate, 9.2nV/√Hz input voltage noise, and 4.91V output swing on 5V supply in a TSSOP-14 package.

For engineers reviewing the OPA4830IPW datasheet, OPA4830IPW pinout, OPA4830IPW application, or OPA4830IPW equivalent, key selection criteria include single-supply operation down to 3V, rail-to-rail input (ground-referenced), high output drive (±75mA @ 5V), low distortion at 5MHz, and quad-channel integration for space-constrained signal conditioning.

Technical Context

The OPA4830IPW employs complementary common-emitter output stages enabling output swing within 220mV of either rail while driving 150Ω loads. Its voltage-feedback architecture supports stable operation with gains ≥ +1 and exhibits peaking-limited frequency response (4dB at G=+1).

It operates across dual supplies (±1.5V to ±5.5V) or single supplies (3V to 11V), with input common-mode range extending below ground and to within 1.8V of V_S+, making it suitable for DC-coupled interfacing to CMOS ADCs and consumer video systems without level-shifting circuitry.

FAQ

What supply voltages does the OPA4830IPW support?

The OPA4830IPW operates on single supplies from 3V to 11V or dual supplies from ±1.5V to ±5.5V. At 5V single supply, it delivers 4.91V output swing and 230MHz bandwidth. Its input common-mode range extends below ground and to within 1.8V of V_S+, enabling true single-supply DC coupling. The OPA4830IPW maintains specified performance across this full range without external level-shifting components.

Does the OPA4830IPW support rail-to-rail input and output?

The OPA4830IPW features rail-to-rail input (including ground on single supply) but not rail-to-rail output. Its output swings to within 220mV of either supply rail when driving 150Ω, delivering 4.91V_PP on 5V supply. This near-rail output capability provides >98% utilization of the available voltage range-sufficient for most 12-bit ADC interfaces and video line drivers without clipping. The OPA4830IPW achieves this via complementary common-emitter output stages.

What is the typical quiescent current of the OPA4830IPW per channel?

The OPA4830IPW draws 4.4mA per channel (17.6mA total) at 5V supply and 25°C, with a maximum of 20mA total across temperature (–40°C to +85°C). This low power consumption enables use in battery-powered portable electronics while maintaining 230MHz bandwidth and 560V/μs slew rate. The OPA4830IPW's current scales predictably with supply voltage and temperature, supporting accurate power budgeting in multi-channel designs.

Can the OPA4830IPW drive a 150Ω load effectively?

Yes-the OPA4830IPW delivers ±75mA output current into 150Ω at 5V supply, enabling direct driving of standard video loads (e.g., 75Ω terminated with 150Ω source) and multiple parallel ADC inputs. Its closed-loop output impedance is just 0.06Ω at ≤100kHz, ensuring minimal gain error under load. The OPA4830IPW maintains 4.78V output swing into 150Ω, preserving signal fidelity without external buffers or gain correction.

How does the OPA4830IPW perform in harmonic distortion at 5MHz?

At 5MHz, 2V_PP output, and RL ≥ 500Ω, the OPA4830IPW achieves –62dBc 2nd-harmonic and –77dBc 3rd-harmonic distortion-critical for clean signal reproduction in PLL integrators and active filters. Distortion improves at lower signal amplitudes, unlike many low-power op-amps. The OPA4830IPW's distortion profile remains stable across supply voltages and temperatures, ensuring consistent spectral purity in demanding mixed-signal applications.
