Product details
Overview
TLV9052IDGKR from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier optimized for low-voltage, high-speed signal conditioning. It delivers 5MHz unity-gain bandwidth, 15V/µs slew rate, ±0.33mV input offset voltage, 330µA per amplifier quiescent current, and operates from 1.8V to 6.0V supply. It is used in precision current shunt monitoring and photodiode amplification where low power and fast settling are critical.
For engineers reviewing the TLV9052IDGKR datasheet, TLV9052IDGKR pinout, TLV9052IDGKR application, or TLV9052IDGKR equivalent, this page provides verified electrical specifications, VSSOP-8 package terminal mapping, real-world use cases in sensor signal chains and motor control feedback loops, and validated alternative options for design flexibility and supply continuity.
Technical Context
The TLV9052IDGKR employs a CMOS input stage with 2pA typical input bias current and integrated RFI/EMI filtering to maintain stability in noisy industrial environments. Its unity-gain stable architecture supports direct use in gain-of-1 configurations without external compensation.
It features rail-to-rail input common-mode range extending 0.1V beyond both supply rails and rail-to-rail output swing within 16mV of each rail at 10kΩ load, enabling full dynamic range utilization in single-supply systems such as battery-powered HVAC controllers and white goods motor drives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 5MHz - enables stable closed-loop operation up to audio frequencies with minimal phase lag |
| Slew rate | 15V/µs - supports fast transient response in pulse-amplification and active filter stages |
| Input offset voltage | ±0.33mV (typ) - ensures <100ppm DC error in 3.3V full-scale current-sense applications |
| Quiescent current | 330µA per channel - allows dual op-amp operation on micro-power rails without compromising speed |
| Supply voltage range | 1.8V to 6.0V - compatible with Li-ion, 3.3V, and 5V system rails without level-shifting |
| Input bias current | 2pA (typ) - minimizes voltage error in high-impedance photodiode and sensor interfaces |
| CMRR | 96dB (typ) - rejects common-mode noise in differential sensing across wide temperature range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | Lower slew rate (1V/µs), higher quiescent current (130µA/channel), 1MHz GBW | Not suitable for >10kHz signal paths or fast-settling current sensing | Select when cost sensitivity outweighs speed/power requirements and bandwidth ≤100kHz suffices |
| OPA2316IDGKR | Higher precision (±25µV VOS), lower noise (11nV/√Hz), same 5MHz GBW and 1.8V–5.5V supply | Better for µV-level sensor signals but higher cost and no shutdown mode | Choose for ultra-low-offset applications where 0.33mV VOS of TLV9052IDGKR is insufficient |
Compared with LMV358IDR and OPA2316IDGKR, the TLV9052IDGKR uniquely balances 15V/µs slew rate, 330µA/channel quiescent current, and ±0.33mV offset in a VSSOP-8 package-making it optimal for cost-constrained, battery-aware industrial sensing where speed and precision coexist.

FAQ
What is the maximum capacitive load the TLV9052IDGKR can drive while remaining stable?
The TLV9052IDGKR maintains stability with capacitive loads up to 150pF, as confirmed by phase margin measurements ≥60° in the datasheet. At 150pF, its slew rate remains ≥15V/µs and overshoot stays below 10%, enabling direct interface to ADC inputs and long PCB traces without isolation resistors.
Does the TLV9052IDGKR support single-supply operation down to 1.8V?
Yes, the TLV9052IDGKR is fully specified for single-supply operation from 1.8V to 6.0V. Its rail-to-rail input extends 0.1V beyond both supply rails and rail-to-rail output swings within 16mV of each rail at 10kΩ load-enabling full dynamic range use in 1.8V systems like portable medical sensors and IoT edge nodes.
What is the input offset voltage drift over temperature for TLV9052IDGKR?
The TLV9052IDGKR has a typical input offset voltage drift of ±0.5µV/°C over –40°C to +125°C, with production distribution showing <2µV/°C max. This low drift ensures minimal calibration drift in temperature-variable environments such as refrigerator compressor control modules.
Can TLV9052IDGKR be used in photodiode transimpedance applications?
Yes, the TLV9052IDGKR is well-suited for photodiode transimpedance amplifiers due to its 2pA typical input bias current, 15nV/√Hz input voltage noise, rail-to-rail input, and unity-gain stability. These characteristics minimize dark-current error and preserve signal-to-noise ratio in low-light detection circuits.
Is the TLV9052IDGKR pin-compatible with other dual op-amps in VSSOP-8 packages?
No, the TLV9052IDGKR uses a standard dual op-amp pinout (IN1+, IN1–, OUT1, V–, V+, IN2–, IN2+, OUT2) matching industry convention-but it is not pin-compatible with legacy parts like LM358 or TLC272 due to differences in internal protection and biasing. Layout reuse requires verification against the TLV9052IDGKR-specific pin map.
