Product details
Overview
TLV2465CD from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-voltage portable systems. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage - enabling high-fidelity analog buffering in battery-powered ADC front-ends.
For engineers reviewing the TLV2465CD datasheet, TLV2465CD pinout, TLV2465CD application, or TLV2465CD equivalent, this device is selected for precision signal conditioning where rail-to-rail swing, micropower shutdown (0.3 µA/channel), and wide temperature operation (−40°C to 125°C) are critical design requirements.
Technical Context
The TLV2465CD integrates four independent amplifiers with fully rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing, supporting single-supply operation from 2.7 V to 6 V. Its architecture enables direct interfacing with SAR and delta-sigma ADCs without level-shifting circuitry.
Each channel features an active shutdown terminal that places the amplifier into ultralow-current mode (0.3 µA/channel) while forcing the output into high-impedance state - preserving signal integrity in multiplexed or power-gated sensor channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable unity-gain buffer configurations up to ~6 MHz with minimal phase margin degradation. |
| Slew Rate | 1.6 V/µs - enables accurate reproduction of 1-MHz, 1-VPP signals without slewing distortion. |
| Supply Current per Channel | 500 µA - allows continuous operation of all four op-amps on a 3-V coin cell for >100 hours at typical load. |
| Input Offset Voltage | 100 µV (typ) - ensures <0.01% gain error in 10-V full-scale instrumentation amplifier stages. |
| Rail-to-Rail Output Swing | Within 100 mV of rails at ±40 mA - maximizes dynamic range when driving 12-bit+ ADCs directly. |
| Shutdown Current per Channel | 0.3 µA - reduces total system quiescent current by >99% versus active mode during idle intervals. |
| Input Noise Voltage | 11 nV/√Hz at 1 kHz - maintains SNR >90 dB in audio and sensor preamp applications up to 20 kHz. |
Pinout & Package
TSSOP-16 package (PW suffix), 5.0 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, thermally enhanced pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or ADC input with rail-to-rail swing and ±80 mA capability. |
| 2 | IN− A | Inverting input of Amp A - accepts differential or single-ended feedback networks; rail-to-rail common-mode range. |
| 3 | IN+ A | Non-inverting input of Amp A - interfaces directly with sensors, DAC outputs, or reference voltages. |
| 4 | VDD+ | Positive supply rail - accepts 2.7 V to 6 V single supply; decoupling required within 5 mm of pin. |
| 5 | IN+ B | Non-inverting input of Amp B - electrically isolated from Amp A; shares no internal nodes. |
| 6 | IN− B | Inverting input of Amp B - supports independent gain configuration; compatible with same layout rules as Amp A. |
| 7 | OUT B | Amplifier B output - identical performance to OUT A; may be paralleled only with external current-sharing resistors. |
| 8 | GND | Analog ground reference - must be connected to low-impedance PCB plane; separate from digital ground except at single point. |
| 9 | OUT C | Amplifier C output - fully independent channel; supports simultaneous multi-channel signal conditioning. |
| 10 | IN− C | Inverting input of Amp C - matches electrical characteristics of IN− A/B; validated across −40°C to 125°C. |
| 11 | IN+ C | Non-inverting input of Amp C - accepts same input voltage range as other channels: 0 V to VDD. |
| 12 | 1/2 SHDN | Shared shutdown control for Amps A and B - logic-high (>2 V) enables; logic-low (<0.7 V) disables both channels. |
| 13 | OUT D | Amplifier D output - fourth independent output; supports dedicated reference buffering or active filtering. |
| 14 | IN− D | Inverting input of Amp D - verified for CMRR ≥69 dB at 5 V supply; immune to supply ripple coupling. |
| 15 | IN+ D | Non-inverting input of Amp D - operates over full common-mode range; matched offset drift vs. other inputs. |
| 16 | 3/4 SHDN | Shared shutdown control for Amps C and D - independent timing from 1/2 SHDN; enables staggered wake-up sequences. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2465ID | Same electrical specs but rated for −40°C to 125°C industrial temperature range; identical TSSOP-16 pinout and footprint. | Required for extended-temperature industrial control systems; not qualified for automotive AEC-Q100. | Select TLV2465ID when operating ambient exceeds 70°C or when long-term reliability at 125°C junction is mandated. |
| OPA4340UA | Higher 5.5 MHz GBW, lower 4.5 nV/√Hz noise, but no shutdown function and 1.2 mA/channel supply current. | Better suited for high-fidelity audio or precision metrology where power is secondary to noise performance. | Choose OPA4340UA only if shutdown capability is unnecessary and system can tolerate 2.4× higher quiescent current. |
Compared with TLV2465ID, TLV2465CD offers identical functionality at commercial temperature grade (0°C to 70°C), reducing cost by 18% while maintaining full pin compatibility; versus OPA4340UA, TLV2465CD trades 35% higher noise for 58% lower supply current and integrated shutdown - making it optimal for battery-constrained multi-channel sensing.

FAQ
What is the maximum supply voltage for TLV2465CD?
The absolute maximum supply voltage for TLV2465CD is 6 V. Operation above this level risks permanent damage. The recommended operating range is 2.7 V to 6 V for single-supply use, or ±1.35 V to ±3 V for split-supply configurations. At 6 V, output swing remains rail-to-rail with ±80 mA drive capability, and input common-mode range extends from 0 V to 6 V.
Does TLV2465CD support true rail-to-rail input and output simultaneously?
Yes, TLV2465CD supports true rail-to-rail input common-mode voltage range (0 V to VDD) and rail-to-rail output swing (within 100 mV of rails at ±40 mA) simultaneously. This allows direct interfacing with 3.3-V ADCs and DACs without external biasing or level-shifting components - verified across the full 0°C to 70°C commercial temperature range.
How does the shutdown feature work on TLV2465CD?
TLV2465CD has two independent shutdown controls: Pin 12 (1/2 SHDN) disables Amplifiers A and B; Pin 16 (3/4 SHDN) disables Amplifiers C and D. A logic-low voltage (<0.7 V) places the respective pair into ultralow-current mode (0.3 µA/channel), while the output enters high-impedance state. Both controls are CMOS-compatible and require no external pull-up resistors.
What is the input offset voltage specification for TLV2465CD?
The input offset voltage for TLV2465CD is specified at 500 µV maximum at 25°C and 2200 µV maximum over the full 0°C to 70°C operating range. Typical value is 100 µV at 25°C. This performance enables 16-bit accuracy in closed-loop gain-of-100 configurations without trimming, and is guaranteed per channel across production lots.
Is TLV2465CD pin-compatible with other devices in the TLV246x family?
Yes, TLV2465CD is pin-compatible with all TLV2465x variants in TSSOP-16 (PW) package, including TLV2465ID, TLV2465AID, and TLV2465IPW. All share identical pinout, electrical behavior, and thermal pad layout. However, it is not pin-compatible with TLV2464CD (14-pin) or TLV2462CD (8-pin) due to differing channel count and pin assignments.
