Product details
Overview
TSH80IYDT from STMicroelectronics is a single, rail-to-rail output, wide-band operational amplifier with standby function, designed for high-fidelity video signal conditioning and A/D converter driving. It delivers 100 MHz bandwidth, 100 V/µs slew rate, and ±55 mA output current into 150 Ω loads while operating from 4.5–12 V single or dual supplies - used in automotive-grade video buffers requiring low THD (0.1%) and precise differential gain/phase (<0.5% / <0.5°).
For engineers reviewing the TSH80IYDT datasheet, TSH80IYDT pinout, TSH80IYDT application, or TSH80IYDT equivalent, key selection criteria include its 100 MHz small-signal bandwidth at AV = +1, 100 V/µs slew rate under 150 Ω load, standby mode switching time (Ton = 2 µs), rail-to-rail output swing, and automotive qualification per AEC-Q100.
Technical Context
The TSH80IYDT employs a high-speed current-feedback architecture optimized for video-frequency operation, supporting closed-loop gains of +1 to +11 and −10 with stable phase margin (>40°) into 150 Ω // 30 pF loads. Its input stage operates over a common-mode range from VCC− to (VCC+ − 1.1 V), enabling robust performance across asymmetric supply configurations.
Standby mode is controlled via a dedicated logic-level enable pin (pin 5), reducing supply current to <10 µA while maintaining high-impedance output (Zout ≈ 10 MΩ || 17 pF). The device is fully characterized at both ±2.5 V and ±5 V dual supplies, as well as +5 V single supply, with guaranteed performance over −40 °C to +85 °C.
Key Specifications

|---|---|
| Bandwidth (−3 dB) | 100 MHz at AV = +1, RL = 150 Ω - supports full NTSC/PAL video bandwidth without attenuation. |
| Slew Rate | 100 V/µs - enables clean 2 Vpp video signals up to 4.5 MHz with <0.5% differential gain error. |
| Output Current | ±55 mA - drives standard 150 Ω video loads with full rail-to-rail swing and minimal distortion. |
| THD | −61 dB (1 Vpp) / −54 dB (2 Vpp) at 4 MHz - meets Hi-Fi and broadcast video linearity requirements. |
| Supply Range | 4.5–12 V single or ±2.5 V to ±5 V dual - compatible with automotive 5 V and industrial 10 V rails. |

Pinout & Package
The TSH80IYDT is housed in an SO8 package (8-pin small outline integrated circuit) with standard pin spacing (1.27 mm), JEDEC MS-012AC compliant, and rated for automotive temperature range (−40 °C to +85 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| VCC+ | Positive supply rail | Accepts 4.5–12 V (single) or +2.5 V to +5 V (dual); decoupling required near pin for stability. |
| VCC− | Negative supply rail | Ground (single supply) or −2.5 V to −5 V (dual); supports asymmetric operation down to VCC− = −1 V. |
| Enable (EN) | Standby control input | Active-high logic input; transitions device between active (ICC ≈ 10.5 mA) and standby (<10 µA) in 2 µs. |
| NC | No connect | Internally unused; must remain unconnected per datasheet layout guidance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6702MA/NOPB | Higher bandwidth (1.8 GHz), no standby mode, SO8 package, higher ICC (12.5 mA), not automotive-qualified. | Targeted at test equipment and broadband comms; lacks AEC-Q100 validation and low-power state. | Select when ultra-wideband gain-flatness (>100 MHz) is critical and automotive compliance is unnecessary. |
| ADA4870ARZ | Higher output current (1 A), wider supply range (±4 V to ±20 V), SO8 package, no standby, higher THD (−48 dB). | Designed for driving heavy capacitive loads (e.g., piezo actuators); over-specified for video line driving. | Select only for high-current, non-video applications where rail-to-rail output and low THD are secondary to drive strength. |
Compared with LMH6702MA/NOPB and ADA4870ARZ, the TSH80IYDT uniquely balances 100 MHz bandwidth, automotive qualification, standby power gating, and 150 Ω video load capability - making it optimal for cost- and power-constrained automotive video systems where reliability and signal integrity are co-prioritized.

FAQ
What is the maximum recommended load capacitance for stable operation of the TSH80IYDT?
The TSH80IYDT remains stable with up to 30 pF of capacitive load when driving a 150 Ω termination, as verified in Figure 3 and Figure 18 of the datasheet. Exceeding 30 pF requires external isolation resistance (≥10 Ω) in series with the output to maintain ≥40° phase margin and prevent peaking or oscillation.
Does the TSH80IYDT support single-supply operation with input referenced to ground?
Yes - the TSH80IYDT supports true single-supply operation with VCC− = GND and VIC ranging from 0 V to (VCC+ − 1.1 V). At VCC+ = 5 V, the input common-mode range is 0–3.9 V, allowing ground-referenced video signals to be amplified without level-shifting circuitry.
How does the standby mode affect output impedance and signal integrity?
In standby mode, the TSH80IYDT disables its output stage, resulting in high-impedance state (Zout ≈ 10 MΩ || 17 pF). This prevents loading of downstream circuits but requires external pull-up/down resistors if DC bias must be maintained on the output node during sleep.
Is the TSH80IYDT pin-compatible with other devices in the TSH8x series?
No - the TSH80IYDT (single-channel, SO8) is not pin-compatible with TSH82 (dual-channel, SO8) or TSH84 (quad-channel, TSSOP-16). While all share identical pin functions per channel, channel count and package footprint differ; PCB layout must be specific to TSH80IYDT's SO8 configuration.
